Interesting... I expected it was doing strchr(aPath, ':') to detect URLS.

Given that ':' "special" for both Windows paths and URLS, why not just 
call strchr(aPath, ':') ? Then we'd catch ftp, **http, mailto, etc. all 
in one fell swoop. Whether to make "file:" (or "file://") a special case 
is technically orthogonal (but probably a good idea).

**BTW, it turns out that Windows and Firefox both do the right thing 
with `http:www.cygwin.com'
