![Ævar Arnfjörð Bjarmason](/assets/img/avatar_default.png)
It's arguably more correct to say "[<option>...]" than either of these forms, but the vast majority of our documentation uses the "[<options>]" form to indicate an arbitrary number of options, let's do the same in these cases, which were the odd ones out. In the case of "mv" and "sparse-checkout" let's add the missing "[]" to indicate that these are optional. In the case of "t/helper/test-proc-receive.c" there is no *.txt version, making it the only hunk in this commit that's not a "doc txt & -h consistency" change.
