The previous commit added tests for shadowing deprecated builtins.
Let’s make the test suite more complete by exercising a sample of
the builtins and in turn test the documentation for git-config(1):
To avoid confusion and troubles with script usage, aliases that hide
existing Git commands are ignored except for deprecated commands.

git-whatchanged(1) is deprecated and you need to pass
`--i-still-use-this` in order to force it to work as before.
There are two affected users, or usages:
1. people who use the command in scripts; and
2. people who are used to using it interactively.
For (1) the replacement is straightforward.[1] But people in (2) might
like the name or be really used to typing it.[3]
An obvious first thought is to suggest aliasing `whatchanged` to the
git-log(1) equivalent.[1] But this doesn’t work and is awkward since you
cannot shadow builtins via aliases.
Now you are left in an uncomfortable limbo; your alias won’t work until
the command is removed for good.
Let’s lift this limitation by allowing *deprecated* builtins to be
shadowed by aliases.
The only observed demand for aliasing has been for git-whatchanged(1),
not for git-pack-redundant(1). But let’s be consistent and treat all
deprecated commands the same.
[1]:
git log --raw --no-merges
With a minor caveat: you get different outputs if you happen to
have empty commits (no changes)[2]

This adds a trace point in start_command so we can see the full
command invocation without having to resort to strace/code inspection.
For example:
$ GIT_TRACE=1 git test foo
git.c:755 trace: exec: git-test foo
run-command.c:657 trace: run_command: git-test foo
run-command.c:657 trace: run_command: 'echo $*' foo
run-command.c:749 trace: start_command: /bin/sh -c 'echo $* "$@"' 'echo $*' foo
Prior changes have made the documentation around the internals of the
alias command execution clearer, but I have still found this detailed
view of the aliased command being run helpful for debugging purposes.
A test case is added to ensure the full command output is present in
the execution flow.

They are equivalents and the former still exists, so as long as the
only change this commit makes are to rewrite test_i18ngrep to
test_grep, there won't be any new bug, even if there still are
callers of test_i18ngrep remaining in the tree, or when merged to
other topics that add new uses of test_i18ngrep.
This patch was produced more or less with
git grep -l -e 'test_i18ngrep ' 't/t[0-9][0-9][0-9][0-9]-*.sh' |
xargs perl -p -i -e 's/test_i18ngrep /test_grep /'
and a good way to sanity check the result yourself is to run the
above in a checkout of c4603c1c (test framework: further deprecate
test_i18ngrep, 2023-10-31) and compare the resulting working tree
contents with the result of applying this patch to the same commit.
You'll see that test_i18ngrep in a few t/lib-*.sh files corrected,
in addition to the manual reproduction.

Before, the `git frotz` command would fail but its return code was
hidden since it was in the upstream of a pipe. Break the pipeline into
two commands so that the return code is no longer lost. Also, mark
`git frotz` with test_must_fail since it's supposed to fail.

Empty arguments passed on the command line can be represented by
a '', however sq_quote_buf_pretty was incorrectly dropping these
arguments altogether. Fix this problem by ensuring that such
arguments are emitted as '' instead.

Introduce a testing suite that is dedicated to aliases.
For now, check only if nested aliases work and if looping
aliases are detected successfully.
The looping aliases check for mixed execution is there but
disabled, because it is blocking the test suite for a full
minute. As soon as there is a solution for loops using
external commands, it should be enabled.
