That's not very helpful to readers.

Something like this?  I am merely guessing why you thought this
change is a good one, but that is what the proposed log message
is supposed to do.

    df70b190 (completion: make stash -p and alias for stash push -p,
    2018-04-20) wanted to make sure "git stash -p <TAB>" offers the same
    completion as "git stash push -p <TAB>", but it did so by forcing
    the $subcommand to be "push" whenever then "-p" option is found on
    the command line.  

    This harms any subcommand that can take the "-p" option---even when
    the subcommand is explicitly given, e.g. "git stash show -p", the
    code added by the change would overwrite the $subcommand the user
    gave us.

    Fix it by making sure that the defaulting to "push" happens only
    when there is no $subcommand given yet.

Thanks.
