I finally tested out my commit privileges with a portion of this old patch:

http://lists.gnu.org/archive/html/m4-patches/2005-09/msg00000.html

(The remainder of the patch was re-proposed by Bruno,
http://lists.gnu.org/archive/html/bug-m4/2006-05/msg00001.html)

2006-05-04  Eric Blake  <address@hidden>

        * Makefile.am (doc/m4.1): Use EXEEXT on built binary.
        Cleanup whitespace.
