Mastering the `patch' and `diff' programs is really essential IMHO :-)

Play around with `-p0', `-p2', ... Note that you should be in groff's
top-level directory while applying such patches so that all
subdirectories can be correctly found if necessary.
In case you are in a git repository, and the patch was incorrectly
applied (this is, only partially, possibly due to a wrong `-pX'
option), say
git reset --hard
to clean up the git repository – of course, this assumes that you
don't have any local changes. If you have, `git stash' stash is your
friend to preserve them.
