ChangeLog, Makefile.in, configure.in, MCONFIG.in, configure, wordwrap.pl:

  Makefile.in (depend): Make "make depend" at the top-level
  	automatically recurse through all subdirectories.
  configure.in: Test for perl since it's needed by wordwrap.pl
  MCONFIG.in (depend): Fix make-depend so that it the dependencies are
  	automatically word-wrapped.  Added the makefile macro $(PERL).
  wordwrap.pl: New file which does the word wrapping.
