On OSX `wc` prefixes the output of numbers with whitespace, such that
the `commit_count` would be "SP <NUMBER>". When using that in

    git submodule update --init --depth=$commit_count

the depth would be empty and the number is interpreted as the pathspec.
Fix this by not using `wc` and rather instruct rev-list to count.

Another way to fix this is to remove the `=` sign after the `--depth`
argument as then we are allowed to have more than just one whitespace
between `--depth` and the actual number. Prefer the solution of rev-list
counting as that is expected to be slightly faster and more self-sustained
within Git.

You meant self-contained, I would guess.

Yes. Mind to fix that locally, or waiting for a resend?

There are a couple of "log --oneline | wc -l" remaining that are
currently safe but they may be a time-bomb waiting to go off.

$ grep -r "log --oneline | wc -l"
t6050-replace.sh: test $(git log --oneline | wc -l) = 7 &&
t6050-replace.sh: test $(git log --oneline | wc -l) = 3 &&
t7406-submodule-update.sh: test 1 = $(git -C submodule log --oneline | wc -l)
t7406-submodule-update.sh: test 1 = $(git -C submodule log --oneline | wc -l)
t7400-submodule-basic.sh: test 1 = $(git log --oneline | wc -l)

All of the occurrences are not white space sensitive AFAICT,
they are just bad examples, which may inspire others to follow
that pattern.

Thanks,
Stefan
