commit 15eb9b11ad91fc55e2d45c038d1fdbce546c847e

    m4/groff.m4: Use separate variable for message.
    
    * m4/groff.m4 (GROFF_TMAC): Use separate shell variable for
      `AC_MSG_RESULT()` content since the human-readable string we populate
      it with in the empty case is not appropriate for later
      `AC_SUBST()`-itution.  Problem introduced by me in commit 19670348, 31
      October.

        * tmac/tmac.am (MOSTLYCLEANFILES): Remove `$(TMACMDOCFILES)`.
        This variable, formerly named `TMACMDOCSTRIPFILES`, should not
        be used in a clean target because its contents are (no longer)
