Personally I think this change will give much less pleasant user
experience.  This is what I currently get:

    $ git reflog <TAB>
    delete  expire  show
    $ git reflog

and after learning the "show" subcommand exists, this is what I would get:

    $ git reflog show <TAB>
    Display all 626 possibilities? (y or n)

With your change, I would get:

    $ git reflog <TAB>
    Display all 629 possibilities? (y or n)

and do not even have a chance to remind myself if the subcommand to drop
a reflog was "delete" or "remove".

At least when I know that I want to be reminded of refs to $verb (use one
of the three subcommands I currently get in place of the "$verb"), I can
say

    $ git reflog $verb <TAB>

and at that point, I am willing to wade thru list of 600+ refs.
