It has the drawback of making debugging with gdb a little harder. Oh well.
Applied anyway (see below).

------------------------------------------------------------------------

Note to Karl: While applying this patch, I got this:

  $ git push
  To ssh://address@hidden/srv/git/gnulib
   ! [rejected]        master -> master (non-fast forward)
  error: failed to push to 'ssh://address@hidden/srv/git/gnulib'

This means that someone did commits at the same time as I. This resolved it:

  $ git stash                   # save my private changes
  $ git pull                    # get the public commits
  $ gitk                        # shows a lozange
  $ git rebase origin/master
  $ gitk                        # shows a linear list of commits again.
  $ git stash apply             # restore my private changes
  $ git push

Note also that the git-merge-changelog program had the effect of avoiding
ChangeLog conflicts during "git pull" and during "git rebase origin/master".
