Is there a way for plugins to do their own parsing and pass
back URLs to be tried?  We have a site (tv2.dk again) that
likes to embed URLs like
/indeks/2|http://producent.tv2.dk/index.php?a=6|links|
and then parse it via JavaScript.  Since we know it does
this, we could parse it down to
<http://producent.tv2.dk/index.php?a=6> and use that link, but
I see no way that a plugin can suggest URLs to the main program.
Should I just overwrite adr and fil that are passed in to
check-link?  That doesn't sound healthy:)
