The key was to put the test after the headers were parsed. It's in the
CVS tree now...

* htdig/Document.cc(readHeader), htdig/HtHTTP.cc(ParseHeader): fix
handling of modification_time_is_now in readHeader, add similar code
to ParseHeader.
I have to admit I'm not familiar with the new HtHTTP code, nor the new
HtDateTime class, so bear with me if I didn't get that part right.

So, basically WWWWoffle tries to mimic the behaviour of the servers that
it caches. I guess my question is still the same, then. Would any server
that honours the if-modified-since header not also emit last-modified
headers? No matter. I think the code handles this properly now.
