[Bf-committers] Undo for extrude function. . .what to do, what to do. . .

[joeedh]

The Extrude function currently doesn't have a BIF_undo_push.  It was 
easy enough to add, but. . .

BIF_undo_push is called twice, once for the extrusion function and once 
for tranform();  So, as a functionality issue, should a user have to 
press U twice to fully undo an extrusion, or should the transform 
function perhaps be hacked to not call BIF_undo_push when in '\n' mode?

Heres a suggestion:  Whether or not to call BIF_undo_push can be passed 
as part of a bitflag passed to transform().  This can be implemented for 
the refactor of the transformation code.  By the way, I really like the 
transformation code. 

Uhh. . .of course this isn't really my domain, but after adding my 
individual faces extrusion function it's been really annoying to have 
undo behave in a wierd fashion.
