This use of eval is unsafe, not really all that useful and can spew
errors that can't be suppressed. So let's remove it, and in future add
a thing that can do expansions in a safe manner
Fixes#6456.
__fish_complete_suffix accepts a first argument containing a
brace-expansion, like
__fish_complete_suffix '.{c,cpp,py}'
We're gonna be removing the `eval` that does that shortly, so let's
remove all uses in our code.
"To assume" and such.
It doesn't check $SHELL, so it might have some other automagic that
can fail (probably still because of the login shell, but I have no
idea).
Override the special variable that
click-completion (https://github.com/click-contrib/click-completion)
uses to force it instead.
Really fixes#6454.

This checks $SHELL to determine which completions to print, and $SHELL
is typically set by your login program.
So if the login shell isn't fish, this will print the wrong
completions.

Turns out we never documented the "jump" ones.
That means the still-undocumented bind functions are
- vi-arg-digit
- vi-delete-to
- and
Mostly because I'd have to look up what they actually *do*, and
possibly rename them to be generic.

It looks like the last status already contains the signal that cancelled
execution.
Also make `fish -c something` always return the last exit status of
"something", instead of hardcoded 127 if exited or signalled.
Fixes#6444
Two blocks of code were trying to do the same thing in different ways;
standardise on one, and only add the compile flags if CMake won't do it
itself (policy CMP0067).
Previously, the block stack was a true stack. However in most cases, you
want to traverse the stack from the topmost frame down. This is awkward
to do with range-based for loops.
Switch it to pushing new blocks to the front of the block list.
This simplifies some traversals.
Work around the issue in CMake where C++ standard doesn't get propagated
to CHECK_CXX_SOURCE_COMPILES. Also correctly check for std::make_unique;
the define was missing from the config.h header.
GCC 4.8 requires the use of `-std=gnu++11` or similar to enable atomic
features. However, older versions of CMake don't pick up the
project-wide target for C++11 when building the configure check targets.
Although CMake policy 0067 could be set to NEW to enable this, it only
exists on CMake 3.8 and newer, while many of our supported platforms are
on an older version.
This was previously required so that, if there was a redirection to a
file, we would fork a process to create the file even if there was no
output. For example `echo -n >/tmp/file.txt` would have to create
file.txt even though it would be empty.
However now we open the file before fork, so we no longer need special
logic around this.
