I don't remember that.  I just did this since then if you look in the
file you have some idea of what it is for.

Automake doesn't use touch because, supposedly, zero-length files
cause problems for some versions of make.  I've never observed this;
it is information I got from somewhere else (maybe the GNU
standards?).
