This command can be used to "`cat`" the contents of `$path` as of `$rev`.
These are "silent" completions, e.g. while this adds a completion for
`git show master:foo`, the completions for `git show <TAB>` are not
affected; these "advanced" completions kick in only after at least
`git show master:<TAB>` to prevent completion pollution or slowing down
tab completions in the typical case (as this would cause each valid and
possibly unique $rev completion result to complete to `n*$rev`
completions for *n* files.

Dealing with macOS output in a fast manner using `string` is surprisingly hard, given that it features lines like
gls(1), ls(1) - list directory contents
Printing the "gls" with the description and the "ls" with the description requires a `while read` loop, and that's too slow.
This reverts commit 7784a5f23c.

* Some comment fixes and renaming of is_iterm2_escape_seq.
The comment for is_iterm2_escape_seq incorrectly says "CSI followed by ]".
This is wrong, because CSI is ESC followed by [ (or the seldom-used 0x9b).
The procedure actually matches Operating System Command (OSC) escape codes.
Since there is nothing iterm2-specific about OSC, is_osc_escape_seq
would be a better name.
Also s_desired_append_char documents a non-existent parameter.
* Update broken iterm2 url in comment.
This was added in 04a96f6 but not strictly required to fix#5803
(verified), with the intention of hiding invisible background jobs
(created by invoking a function within a pipeline) from the user, but
that also broke intentionally created jobs from displaying as well.
I'm thinking it can't be done without keeping track of caller context vs
job context.
Closes#5824.
env_scoped_t lives between environment_t and env_stack_t.
It represents the read-only logic of env_stack_t and will be used to back
the new environment snapshot implementation.
These tests used raw, unescaped parentheses to perform `test` logical
grouping, but the test failures weren't caught because the parser
evaluation errors were not being propagated (fixed in bdbd173e).
It was unconditionally returning `parse_execution_success`. This was
causing certain parser errors to incorrectly return after evaluation
with `$status` equal to `0`, as reported after `eval`, `source`, or
sub-`fish` execution.
Prior to this change, fish used a global flag to decide if we should check
for changes to universal variables. This flag was then checked at arbitrary
locations, potentially triggering variable updates and event handlers for
those updates; this was very hard to reason about.
Switch to triggering a universal variable update at a fixed location,
after running an external command. The common case is that the variable
file has not changed, which we can identify with just a stat() call, so
this is pretty cheap.
