contrib: contacts: interpret committish akin to format-patch

Browse Source 
As a convenience, accept the same style <since> committish as accepted
by git-format-patch. For example:

  % git contacts origin

will consider commits in the current branch built atop 'origin', just as
"git format-patch origin" will format commits built atop 'origin'.
