The test case added by 9466e3809d ("blame: enable funcname blaming with

One variable that the test case introduces will not have IFS characters
and could remain without quotes, but let's quote all expansions for
consistency, not just the one that has the path name.

Using "1~5" isn't portable. Nobody seems to have noticed, since perhaps
people don't tend to run the perf suite on more exotic platforms. Still,
it's better to set a good example.
We can use:
perl -ne 'print if $. % 5 == 1'
instead. But we can further observe that perl does a good job of the
other parts of this pipeline, and fold the whole thing together.

We allow variadic macros in the code base, but only if there is fallback
code for platforms that lack it. This leads to some annoyances:
- the code is more complicated because of the fallbacks (e.g.,
trace_printf(), etc, is implemented twice with a set of parallel
wrappers).
- some constructs are just impossible and we've had to live without
them (e.g., a cross between FLEX_ALLOC and xstrfmt)
Since this feature is present in C99, we may be able to start counting
on it being available everywhere. Let's start with a weather balloon
patch to find out.
This patch makes the absolute minimal change by always setting
HAVE_VARIADIC_MACROS. If somebody runs into a platform where it's a
problem, they can undo it by commenting out the define. Likewise, if we
have to revert this, it would be quite unlikely to cause conflicts.
Once we feel comfortable that this is the right direction, then we can
start ripping out all the spots that actually look at the flag, and
removing the dead code.

The CI/PR GitHub Actions workflow uses the 'matrix' strategy for the
"windows-test", "vs-test", "regular" and "dockerized" jobs. The default
behaviour of GitHub Actions is to cancel all in-progress jobs in a
matrix if one of the job of the matrix fails [1].
This is not ideal as a failure early in a job, like during installation of
the build/test dependencies on a specific platform, leads to the
cancellation of all other jobs in the matrix.
Set the 'fail-fast' variable to 'false' for all four matrix jobs in the
workflow.

'./t1234-foo.sh --stress-jobs=X ...' is supposed to run that test
script in X parallel jobs, but the number of jobs specified on the
command line is entirely ignored if other '--stress'-related options
follow. I.e. both './t1234-foo.sh --stress-jobs=X --stress-limit=Y'
and './t1234-foo.sh --stress-jobs=X --stress' fall back to using twice
the number of CPUs parallel jobs instead.
The former has been broken since commit de69e6f6c9 (tests: let
--stress-limit=<N> imply --stress, 2019-03-03) [1], which started to
unconditionally overwrite the $stress variable holding the specified
number of jobs in its effort to imply '--stress'. The latter has been
broken since f545737144 (tests: introduce --stress-jobs=<N>,
2019-03-03), because it didn't consider that handling '--stress' will
overwrite that variable as well.
We could fix this by being more careful about (over)writing that
$stress variable and checking first whether it has already been set.
But I think it's cleaner to use a dedicated variable to hold the
number of specified parallel jobs, so let's do that instead.
[1] In de69e6f6c9 there was no '--stress-jobs=X' option yet, the
number of parallel jobs had to be specified via '--stress=X', so,
strictly speaking, de69e6f6c9 broke './t1234-foo.sh --stress=X
--stress-limit=Y'.

During a merge conflict, the name of a file may appear multiple
times in "git ls-files" output, once for each stage. If you use
both `--delete` and `--modify` at the same time, the output may
mention a deleted file twice.
When none of the '-t', '-u', or '-s' options is in use, these
duplicate entries do not add much value to the output.
Introduce a new '--deduplicate' option to suppress them.

ls-refs performs a single revision walk over the whole ref namespace,
and sends ones that match with one of the given ref prefixes down to the
user.
This can be expensive if there are many refs overall, but the portion of
them covered by the given prefixes is small by comparison.
To attempt to reduce the difference between the number of refs
traversed, and the number of refs sent, only traverse references which
are in the longest common prefix of the given prefixes. This is very
reminiscent of the approach taken in b31e2680c4 (ref-filter.c: find
disjoint pattern prefixes, 2019-06-26) which does an analogous thing for
multi-patterned 'git for-each-ref' invocations.
The callback 'send_ref' is resilient to ignore extra patterns by
discarding any arguments which do not begin with at least one of the
specified prefixes.
Similarly, the code introduced in b31e2680c4 is resilient to stop early
at metacharacters, but we only pass strict prefixes here. At worst we
would return too many results, but the double checking done by send_ref
will throw away anything that doesn't start with something in the prefix
list.
Finally, if no prefixes were provided, then implicitly add the empty
string (which will match all references) since this matches the existing
behavior (see the "no restrictions" comment in "ls-refs.c:ref_match()").

Correctly initialize the "prefixes" strvec using strvec_init() instead
of simply zeroing it via the earlier memset().
There's no way to trigger a crash, since the first 'ref-prefix' command
will initialize the strvec via the 'ALLOC_GROW' in 'strvec_push_nodup()'
(the alloc and nr variables are already zero'd, so the call to
ALLOC_GROW is valid).
If no "ref-prefix" command was given, then the call to
'ls-refs.c:ref_match()' will abort early after it reads the zero in
'prefixes->nr'. Likewise, strvec_clear() will only call free() on the
array, which is NULL, so we're safe there, too.
But, all of this is dangerous and requires more reasoning than it would
if we simply called 'strvec_init()', so do that.
