Here's mine.  I think this can be improved over time, so my only comment is that
paths should have a / at the front

*.user

*.ncb

*.suo

File .gitignore (right):

Line 33: /webkit/data/
Isn't this where we keep our layout test results?  I think you want:
webkit/data/layout_tests/LayoutTests

It would also be nice to have /out/ which is the make output directory.

Also, this list doesn't seem to include all the src-internal repositories, but
maybe that's not a big deal?
