[svn] Makefile.in (distclean): sample.wgetrc.munged_for_texi_inclusion needs to be
included in the distribution or it'll get regenerated due to the wget.info
dependency, and then that file will get regenerated, forcing people to have
makeinfo installed unnecessarily.  We could use a kludge of a 0-length file in
the distro, but the file isn't that big and should compress very well.

wget.texi: Changed "VERSION 1.5.3+dev" to "VERSION 1.7-dev" and "UPDATED Feb
2000" to "UPDATED Dec 2000".  Like the comment in the file says, it'd be nice if
these were handled automatically...
