[Groff] Adding groffer new directories to Makefile.in

[bernd . warken]

The actual groffer version has 2 subdirectories (perl/ and shell/)
that do not have a Makefile.sub.  Does it make sense to add this
information to the top Makefile.in to variable NOMAKEDIRS:

$ diff -u Makefile.in.orig Makefile.in
--- Makefile.in.orig    2006-05-30 19:29:09.000000000 +0200
+++ Makefile.in 2006-10-23 23:52:17.000000000 +0200

 NOMAKEDIRS=\
   arch/djgpp \
+  contrib/groffer/perl \
+  contrib/groffer/shell \
   contrib/hdtbl/examples \
   contrib/mm/examples \
   contrib/mm/mm \

Is it possible to edit Makefile.in, or was it generated by
autoconf/automake?  Then it just has to be regenerated.
