    Remove subsumed repetitions in regexps · 770f76f0
    Mattias Engdegård authored
    Make regexps smaller and faster by removing terms that are superfluous
    by virtue of standing next to another term that matches more.  See
    https://lists.gnu.org/archive/html/emacs-devel/2020-01/msg00949.html
    for details.
