completion: make stash -p and alias for stash push -p

tgummerer · gitster · commit df70b190bdd2 · 2018-04-20T10:39:50.000+09:00
We define 'git stash -p' as an alias for 'git stash push -p' in the
manpage.  Do the same in the completion script, so all options that
can be given to 'git stash push' are being completed when the user is
using 'git stash -p --&lt;tab&gt;'.  Currently the only additional option
the user will get is '--message', but there may be more in the future.
