143757e8c6 Expand wildcards on tab
Prior to this change, if you tab-completed a token with a wildcard (glob), we
would invoke ordinary completions. Instead, expand the wildcard, replacing
the wildcard with the result of expansions. If the wildcard fails to expand,
flash the command line to signal an error and do not modify it.

Example:

    > touch file(seq 4)
    > echo file*<tab>

becomes:

    > echo file1 file2 file3 file4

whereas before the tab would have just added a space.

Some things to note:

1. If the expansion would produce more than 256 items, we flash the command
line and do nothing, since it would make the commandline overfull.

2. The wildcard token can be brought back through Undo (ctrl-Z).

3. This only kicks in if the wildcard is in the "path component
   containing the cursor." If the wildcard is in a previous component,
   we continue using completions as normal.

Fixes #954.

1023d322e5 Rationalize tilde unexpansion
When fish expands a string that starts with a tilde, like `~/stuff/*`, it
first must resolve the tilde (e.g. to the user's home directory) before
passing it to wildcard expansion. The wildcard expansion will produce full
paths like `/home/user/stuff/file`. fish then "unexpands" the home directory
back to a tilde.

Previously this was only used during completions, but in the next commit
we plan to use it for string expansions as well.

Rationalize this behavior by adding an explicit flag to request it and
explain some subtleties about completions.

cfbebb7201 Better support for helper functions in pexpect
When a pexpect test fails, it reports the "failing line." Prior to this
commit, it did so by walking up the Python call stack, looking for
the first frame which is not in the pexpect_helper module, and so presumably
in the test itself. However sometimes the test wants to define a helper
function; then if the test fails the helper function is reported as the
failing line, not the callsite of the helper.

Fix this by skipping functions which have the `callsite_skip` attribute set.

Nothing to relnote here.

32ed0b80da Don't erase job status message when using multiline prompt
As explained in the parent commit, if we print things to the command line,
we move the cursor down before redrawing a multi-line prompt.  This is a
workaround to avoid erasing what we printed.

We forgot to do add this workaround to fish_job_summary. When running
`sleep 1 &` with a multiline prompt, the job exit notification is immediately
overwritten (most of the time).  This can be observed consistently on Linux
by waiting before redrawing:

    diff --git a/share/functions/fish_job_summary.fish b/share/functions/fish_job_summary.fish
    index a552fabbc..f457ee8e8 100644
    --- a/share/functions/fish_job_summary.fish
    +++ b/share/functions/fish_job_summary.fish
    @@ -52,6 +52,7 @@ function fish_job_summary -a job_id is_foreground cmd_line signal_or_end_name si
         string repeat \n --count=(math (count (fish_prompt)) - 1) >&2

         if test $is_foreground -eq 0; and test $signal_or_end_name != STOPPED
    +        sleep 1
             commandline -f repaint
         end
     end

Move the cursor down to work around this. In future, we could avoid calling
fish_prompt.  Also, this solution add an extra blank lines before the next
prompt.  With a real fix, we could get rid of that. Even worse, sometimes
there are two blank lines instead of one (for a two-line prompt).

Fixes #8817

b28a18be73 Simplify cursor movement for multi-line prompts before repainting
We have some key bindings that print directly to the terminal while the user
is still typing the command line. Thereafter, we redraw the command line,
so the user can resume typing. To redraw a multiline command line, we first
erase several lines above the cursor. To not erase the key bindings' output,
we move the cursor down that many lines.

Simplify the logic; no functional change.

1c7b934402 Revert "Replace some simple loops with STL algorithms"
This commit was problematic for a few reasons:

1. It silently changed the behavior of argparse, by switching which
characters were replaced with `_` from non-alphanumeric to punctuation.
This is a potentially breaking change and there doesn't appear to be any
justification for it.

2. It combines a one-line if with a multi-line else which we should try
   to avoid.

789b2010f5 Don't use a function variable in alias
This conditionally set a function variable in an unsafe way.

If you do something like

```fish
if condition
   set -f foo bar

then, if the condition was false, $foo could still use a global variable.

In this case, alias would now fail if a variable $wraps was defined globally.

translations but then we'd need a real string freeze with a
translation team for those to be worth anything anyway, soo)

e717b13e75 Fix spurious syntax error on escaped $@ inside quoted command substitution
We detect use of unsupported features like $@ by scanning string tokens
as a whole. With quoted command substitution, this has false positives,
as reported in [1]. We already recursively run the same error checks on
command substitutions, so limit the remaining checks to the gaps in-between
command substitutions.

3e3f507012 Fix regression expanding \$()
When expanding command substitutions, we use a naïve way of detecting whether
the cmdsub has the optional leading dollar. We check if the last character was
a dollar, which breaks if it's an escaped dollar.  We wrongly expand
\$(echo "") to the empty string. Fix this by checking if the dollar was escaped.

The parse_util_* functions have a bunch of output parameters. We should
return a parameter bag instead (I think I tried once and failed).

1b668f5675 Don't use results of quoted command substitution in adjacent variable expansion
Given

    set var a
    echo "$var$(echo b)"

the double-quoted string is expanded right-to-left, so we construct an
intermediate "$varb".  Since the variable "varb" is undefined, this wrongly
expands to the empty string (should be "ab"). Fix this by isolating the
expanded command substitution internally. We do the same when handling
unquoted command substitutions.

793aff3891 Use -fno-c++-static-destructors
Static destructors cause the destructor for a global object to run when
the program exits. They are bad because:

1. Registering them takes time and memory at startup

2. Running them takes time at shutdown and also they may have weird
   interactions.

This shaves about 12k off of the binary size.

Unfortunately gcc does not support this flag.

108fe574a0 Finally track down that cursed read test failure
The read.fish check has a test where it limits the amount of data passed to
`read` to 8192 bytes, and verifies that fish reads exactly that amount.
This check occasionally fails on the OBS builds; it's very hard to repro a
failure locally, but I finally did it.

The amount of data written is limited via `yes` and `dd`:

    yes $line | dd bs=1024 count=(math "$fish_read_limit / 1024")

The bug is that `dd` outputs a fixed number of "blocks" where a block
corresponds to a single read. As `yes` and `dd` are running concurrently,
it may happen that `dd` performs a short read; this then counts as a single
block. So `dd` may output less than the desired amount of data.

This can be verified by removing the 2>/dev/null redirection; on a
successful run dd reports `8+0 records out`, on a failed run it reports
`7+1 records out` because one of the records was short.

Fix this by using `fullblock` so that dd will no longer count a short read
as a single block. `head` would probably be a simpler tool to use but we'll
do this for now.

Happily it's not a fish bug. No need to relnote it.
