This change is a bit surprising here. Why is this necessary? I
thought parse_options would handle no arguments just fine?

This is a bit different than what the current code does. Currently
the rules for when a plain 'git stash' becomes 'git stash push' are
the following:
- If there are no arguments.
- If all arguments are option arguments.
- If the first argument of 'git stash' is '-p'.
- If the first argument of 'git stash' is '--'.
This is to avoid someone typing 'git stash -q drop' for example, and
then being surprised that a new stash was created instead of an old
one being dropped, which what we have above would do.
For more reasoning about these aliasing rules see also the thread at [1].
