[Mediawiki-l] Help: where do I hack to change link output?

[Jeremy G Byrne]

Hi All--

[I posted this in a different form last week, but didn't get a
definitive reply.]

I'm trying to work out what or where I need to hack the php
code to alter the way "broken local links" (ie. references to
pages which aren't in the wiki, which are normally transformed
into "&action=edit" style links) are displayed.

I have looked in the obvious places--Linker.php and Skin.php--but
I can't seem to locate the relevant function, and more general
research has turned up nothing.

Can anyone shed some light, please?

CYa,
JEREMY
