gbranden pushed a commit to branch master
in repository groff.

commit 7da376ae9857562ce0ae2d65f03f5fd97e28fd2b
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Tue Jul 27 19:46:07 2021 +1000

    [nroff]: Fix oversights.
    
    * src/roff/nroff/nroff.sh: Fix straggling use of `$1`, which might not
      have a clear meaning in some shells after being shifted (what if we
      just shifted the last argument?).  Also `continue` after processing a
      (groff) option argument, as we should make no attempt to parse it.
    
    Should have been part of 2b955c57, 20 July.

        * src/roff/groff/tests/regression_savannah_59202.sh: Remove any
        core file before running troff so we don't throw a false
        positive.
