The test and [ commands are used throughout the prompt generation.  They
also happen to be valid function names that can be defined, leading to
unintentional results.  Prevent the somewhat unusual case of this
happening by simply using [[, which is reserved.

Hmm. I do think we need to be a bit more paranoid about style in the
prompt and completion code, because they are sourced into the user's
shell alongside whatever other weird customizations they'd have. So we
already have adjustments to work under "set -u", and so forth.

But at some point we may say "you have made the environment too hostile
for us to function". Is redefining "test" to something that doesn't
behave the same way such a case? Part of me wants to say yes. :)

That said, if it's not _hard_ to support, maybe it is worth doing to be
on the cautious side? A few thoughts:

  - my biggest concern on cost is that this is an unusual style for our
    project (which usually writes in POSIX shell, though of course this
    file is meant to be bash/zsh specific). Will it be a maintenance
    burden going forward?

  - this only changes git-prompt.sh; doesn't the completion code have
    the same issue?

  - I don't write much bash-specific code, but I seem to recall that
    "[[" has some subtle differences to "[". Is it sufficiently a
    superset that these conversions are all equivalent?

    I think some like:

> -	if [ $pcmode = yes ] && [ $ps1_expanded = yes ]; then

    are not equivalent, but it's an actual improvement (bash's builtin
    "[[" isn't confused by unquoted empty variables), but I don't know
    if there may be other gotchas.

    (I doubt this is an actual bug in the current code, as $pcmode
    always seems to be set, but just a more defensive style).

I'd be inclined to agree!  But disregarding a user with malicious
intent, these environment changes can also be unintentional: I came
across it when I stubbed out a quick test() function while prototyping
something unrelated.

That's possible, but I suspect the burden is minimal.  As you said, this
is bash and zsh specific, and for those shell coders who only write
Bourne dialect it's to be read as a "strong" left square bracket.  For
example, to minimize any shock to the eyeballs I've intentionally not
re-written string operations `[ a = b ] && [ c = d ]` to `[[ a == b && c
== d ]]`.  I promise it wasn't mere laziness!

>   - this only changes git-prompt.sh; doesn't the completion code have

It does.  Although there has been some movement towards the
bash-specific builtin:

    $ git show v2.36.1:./git-completion.bash | awk '
      /(^\[|[^[]\[) |\<test\>/ && !++slb || /\[\[ / && !++dlb || 0;
      END { print slb, dlb; }'
    119 15
    $

This can be addressed in a future patch.

Yeah, there's no word splitting or pathname expansion.  Also, bash4
onwards changed the < and > operators within [[ to locale order rather
than ASCII.

I kind of wonder what else would have trouble with your accidental
breakage. I poked at the bash-completion package as the only other
prominent "source this into your bash script" package I could think of.
They do indeed seem to mostly avoid "test", though there are a few cases
in program-specific completions.

In the general case, though, I think it's an infinite rabbit hole. I can
similarly redefine "declare" or "local" and cause all sorts of trouble.
And there's no real defense for scripts there.

I guess my concern was less about doing it once, and more about: is this
something we want to continue enforcing as time goes on? That is, would
we want to catch it in review and complain about people using "test"?
That's a subtle thing to remember to look for, though I guess we could
automate it via the tests. Or would we rely on people who cared to
notice new instances and submit patches? That's how we deal with some
other portability issues (if nobody is screaming, how broken could it
be?). But it sounds from your description like this was a one-off even
for you.

So I dunno. I'm not really opposed, but I'm not convinced it's really
accomplishing much here.

Yes, if this is just a mental exercise burning off excess calories
and too much spare time and nothing else, I'm hesitant to burden our
reviewers and casual contributors, who do not have excess calories
or too much spare time to burn off just to play nice with the result
of this patch, with an issue that is apparently only theoretical
like this one, with which nobody actually is hurt in practice.

It's not like local variables used in prompt and completion leaking
out, which can hurt real users (as it is quite normal to use throw
away variables in your interactive sessions).  It's not even like
these scripts being "set -u" clean, that may hurt those who use "set
-u" in their interactive sessions (what for?) but nobody else.  

If you write your own shell function "test" that is grossly
incompatible with everybody else's "test", where do you do that?
Not in your .bashrc, or you would break more than just prompt and
completion.

If this came with additions to t9903 that redefines "test" and tries
to make sure we consistently use bashism [[...]] and such a change
to "test" would not break it, I might have been more sympathetic,
but I dunno.  I sort-of like the purity of mind when we say "this is
a #!/bin/bash script and we maximally write in a way a bash-script
expert would", but many of our shell scripts outside these two
contrib/ scripts HAVE to be portable and free of bashisms, so...

I guess I am mostly on the same page here.
