Making `true` into a builtin is a significant optimization to `while
true` loops. As long as `true` is a builtin, we may as well make `false`
builtin as well (despite the fact that it's not typically executed in a
loop).
This makes two changes to parse trees:
1. Unmaterialized nodes no longer have an invalid source location
For example, with the code `while false;end` there are no tokens
associated with the while loop's job_list, and therefore it is
unmaterialized. Previously it would have had a SOURCE_OFFSET_INVALID.
But now it has a zero source length, but an offset equal to the end of
the while loop (i.e. the semicolon), and a zero length. Correspondingly,
the has_source function now checks the length instead of the offset.
2. Special (comment and error) nodes have always been "disconnected,"
meaning they are not the child of any other node. However, they now have
their parent offsets set to whatever the top of the node stack was when
the node was encountered. This gives us a sense of which node the
comment is "in", e.g. if we are constructing a job list then the
comment's parent will be the job list. This lets us determine the
comment's indent.
All opam subcommands and descriptions are covered, along with
all the flags that are common to all commands. However, only
`opam config` has complete subsubcommand coverage.
Apparently, in zsh, Meta+H can be used to display the manpage for
the current command. This commit adds this zsh feature to fish shell.
The F1 keybinding is left, although it's now secondary according to
fish help, as some terminal emulators don't let the user press F1 key.
my_wcswidth() was just a wrapper around fish_wcswidth() already.
Instead, add two convenience overrides of fish_wcswidth() to common.h
that make it a drop-in replacement for my_wcswidth().
If a wildcard or completion expands to a file that begins with
one or more dashes, prepend a ./ to it so that it doesn't get
parsed as an option.
Fixes#1519
history_lru_node_t has implicit destructor defined. However, because
it's being deleted as lru_node_t, it's not being actually called, as
lru_node_t doesn't have a virtual destructor.
It seems expect prioritizes the first pattern in the list, instead of
the pattern that matches earliest in the buffer. That seems pretty
stupid, but let's try moving the prompt pattern to the end and see if
that fixes the Travis failures.
Also tweak colored output to reset before the newline instead of after,
so travis behaves better (for some reason reset causes travis to display
the line in black).
Split test_interactive off from test_fishscript and add a new target
test_high_level that tests both.
Add some Makefile magic so the tests can be run serially without using
sub-make, which gets rid of a little noise from the make output.
Rewrite interactive tests to look better.

As this is rendering ok in Firefox, this version should pickup the best
fonts for most browser/os variants based on 'font-stretch' support.
`.fish_left_bar` should be condensed, the main body font shouldn't.
Binds with the same sequence in multiple modes was not working right.
Fix up the implementation to propagate modes everywhere as necessary.
This means that `bind` will properly list distinct binds with the same
sequence, and `bind -e` will take mode into account properly as well.
Note that `bind -e seq` now assumes the bind is in the default bind
mode, whereas before it would erase the first binding with that sequence
regardless of mode.
`bind -e -a` still erases all binds in all modes, though `bind -M mode
-e -a` still only erases all binds in the selected mode.
<em> used to represent something else, but as far as I can tell, all
uses of <em> in the documentation today actually represent text that's
supposed to be visibly different. Notably, the documentation on
supported escapes uses <em> to indicate the letters that are a
placeholder for e.g. a hex digit, as opposed to being a literal
character.
