in repository groff.

commit 73d3c0c6f0b3c9845c3414741f6c707d93200321

    configure.ac: Fix code style nits; tweak report.
    
    * configure.ac: Fix code style nits and tweak report.  Stop
      superfluously using braces for shell parameter expansions that don't
      require them.  The shell is not make(1).  Say "installation
      _directory_ prefix" since another kind of prefix can be used by groff
      (the "g" in front of command and macro package names shared with AT&T
      troff).
