I think there is no need to do that, I have that in my code already 
(although in a different form). My implementation reflects what C git does.

it's in my local repo. I have no public repo

I've been asking Shawn about input a few times but did not receive any 
yet. he wants it moved into a treewalk but I'm way too unfamiliar with 
that code to do it properly (and easily)

the reason that I have a lot of eclipse specific stuff in there is because 
I just started implementing the handling in the egit plugin since that was 
the easiest point to plug it into.

I have been thinking a lot about getting rid of the eclipse specific stuff 
and I think that's not hard. it requires a bit of reworking of the code 
but what I have in mind is actually a lot cleaner that what I sent out 
earlier.

that would be easy

I think it would be easier to let eclipse manipulate the ignore file and 
then just re-read it into the 'ignore cache'

see remark above. exactly what I had in mind. git does ignore handling 
like cvs.

no account yet.
would be nice to work on this with other people.
