HTRDF.c parser performance improvement

Good day,

I've been using the libwww HTRDF component for parsing files. I made a
recent change (diff of HTRDF.c output below) that has improved the
parsing process. In my case, parsing time went from 74 minutes to 4
minutes on a file with a 300K elements. I am not an official hacker and
do not have write access to the CVS repository. So I offer my
contribution via this email. The fix is based on the latest HTRDF.c
file. I attached the updated HTRDF.c file for your revision. Assuming
this is 'hacker approved', can someone put this into the CVS repository?

Regards,

David Brown
