ChangeLog, Makefile.in, MCONFIG.in:
  Makefile.in: Use && after a cd command so that the right thing happens
  	if the directory is missing.  Don't compile man pages upon
  	installation any more, since modern Linux systems don't have
  	/usr/man/cat? anymore (they typically cache man pages in /var/catman
  	and delete them if they haven't been used in a while, to save on disk
  	space, and because CPU's are fast enough these days that you can get
  	away with this).
  MCONFIG.in: Add a new makefile variable for the share directory (i.e.,
  	/usr/share).  Make an autoconf magic make rule so that
  	$(top_builddir)/util/subst.conf gets rebuilt automatically when
  	necessary.
