wwwdocs/bin/preprocess - patch to give zero on success

[Hans-Peter Nilsson]

Hi.

The script "preprocess" always gives nonzero (i.e. 1) exit status.
That's not good when it's used to check success, as by the htdig
update script (no, it's not fatal).

I must confess I managed to reset the dates of all web documents
by accidentally invoking preprocess with no arguments. :-(

Ok to install?
