I don't think libwww is the only available library that can parse URLs and
return the file name part for you. I fully agree that linking with libww for
the sole purpose of parsing URLs, is a waste.

I agree that this suggestion borders to what I object against, but I see a
clear distinction: checkproto would be focused on returning what protocol
libcurl would USE on the given URL. Not necessarily what the protocol part
says, and it would return not-supported if the specified protocol part isn't.
Thus, it isn't just about parsing the URL and returning the protocol part.

Not quite, as then you'd also get the URL transfered if you provided a URL
with a supported protocol.
You could however use the curl_version_info() to extract most of this info,
yes, but then you still wouldn't know for sure what protocol libcurl will use
when specifying a host name like 'curl.haxx.se' or 'ftp.sunet.se'. This
function would tell.

The connection between the given URL and how libcurl works. Code to extract
the file name part needs no knowledge whatsoever about libcurl internals.

Thanks! I've applied, verified and committed it.
