in repository groff.

commit ae59ee569eb5cddab8bdf12a8009bd1b907a8205
Author: G. Branden Robinson <address@hidden>
Date:   Tue Nov 7 14:23:39 2017 -0500

    tmac/strip.sed: Remove nilpotent capture.
    
    Captures are useless if not backreferenced.  And in this case,
    potentially confusing because the substitution match pattern also
    performs a capture.
