Hi Adam, hope you don't mind another minor nitpick ...

I still see this in stow's Makefile.am:

  CLEANFILES = $(bin_SCRIPTS) $(pm_DATA) $(dist_man_MANS) $(HTML) $(PDF) ChangeLog

which means that the distributed files $(dist_man_MANS), $(HTML), $(PDF)
and ChangeLog will still be removed by "make clean".  IMHO the following
would be better:

  CLEANFILES = $(bin_SCRIPTS) $(pm_DATA)
  MAINTAINERCLEANFILES = $(dist_man_MANS) $(HTML) $(PDF) ChangeLog

Also, the dependencies:

  dist-hook: $(dist_man_MANS) ChangeLog
  ChangeLog: doc/ChangeLog.OLD

will not ensuere that the ChangeLog will be remade at "make dist"
time, even if it is out-of-date w.r.t. the current git repository.

The following should offer a workaround, by forcing ChangeLog to
be rebuilt unconditionally upon creation of distribution tarballs
(untested!):

 dist-hook: $(dist_man_MANS)
## If we are creating a distribution from a git checkout, ensure
## the ChangeLog file is in sync the git repository.
	if test -d $(top_srcdir)/.git; then \
	  rm -f ChangeLog \
	    && $(MAKE) $(AM_MAKEFLAGS) ChangeLog \
	    && cp -f ChangeLog $(distdir)/ChangeLog; \
	else :; fi;
