No. I am not thinking about that. I do not think it is a big loss
if the helper cannot be used in non-repository.

No. I am not thinking about that, either.

Let's not go back that far. This is taken from v4 (t/t6400) ...
local ops val &&
if test "$#" -le 2
then
BUG "Expect 2 or more arguments"
fi &&
ops="$1" &&
val="$2" &&
shift 2 &&
mkdir -p .git/trash &&
"$@" >.git/trash/output &&
test_line_count "$ops" "$val" .git/trash/output
... except that it runs '"$@"' instead of 'git ls-files "$@"', so
that we could try running things other than ls-files, and that would
be mostly good enough. We may want to be prepared for a caller who
wants to use the helper from within a subdirectory by not hardcoding
".git/trash", though. Something along the lines of ...
local ops val &&
+ local trashdir=$(git rev-parse --git-dir)/trash &&
if test ...
...
- mkdir -p .git/trash &&
- "$@" >".git/trash/output" &&
- test_line_count "$ops" "$val" .git/trash/output
+ mkdir -p "$trashdir" &&
+ "$@" >"$trashdir/output" &&
+ test_line_count "$ops" "$val" "$trashdir/output"
