[Mediawiki-l] Pointing broken links elsewhere than "edit"

[Jeremy G Byrne]

Hi All--

I'm trying to hack whatever functions produce the "&action=edit"
style defaults for broken links, but despite trawling Linker.php
and Skin.php (and a couple of less-likely candidates), googling
randomly and looking through the list archives here, I can't work
out what to change.

Can someone please point me in the right direction, or suggest
a better way to go about this? (My intention is to allow a
setting in LocalSettings.php to specify where broken links
point--which could be onsite or offsite, eg. to the wikipedia
page of the same name)? Thanks.

CYa,
JEREMY
