Launchpad should treat SourceForge and GForge URLs differently when creating bug watches

[Fole]

When I try to add a link to the upstream tracker for Oregano, the system generates an invalid link to the upstream page.
I used this link:
http://gforge.lug.fi.uba.ar/tracker/index.php?aid=1307
This itself works fine, however Launchpad translates this to
http://gforge.lug.fi.uba.ar/support/tracker.php?aid=1307
which does not work. Additionally, it cannot connect to Oregano bugs and retrieve information from there.

I forgot to mention that the bug where I tried this is https://bugs.launchpad.net/oregano/+bug/60777

This is because Launchpad is treating GForge URLs in the same way as it treats SourceForge URLs. The problem is that they're very similar - Launchpad identifies them using the same regular expression.
