Duh, thanks for that suggestion. But actually the decimal character
constant for an "_" is 95, which is 5F in hex. So the URI would be:
http://www.example.com/my%5Ffile%5Fname.htm
which did the trick nicely.

Yeah that would be nice, but your suggestion of escaping based on rfc2396
works perfectly and suits my needs.

I suppose, but I interpret what I read on the man page literally. I can
accept that it isn't a bug, but a mention in the man page that ANY string
enclosed by a "_" character will be parsed as a variable even if it isn't
one would be nice.
Thanks for the help,
Matt
