[svn] * wget.texi (Download Options): --no-clobber's documentation was
severely lacking -- ameliorated the situation.  Some of the
previously-undocumented stuff (like the multiple-file-version numeric-suffixing)
that's now mentioned for the first (and only) time in the -nc documentation
should probably be mentioned elsewhere, but due to the way that wget.texi's
hierarchy is laid out, I had a hard time finding anywhere else appropriate.
