Patch Set 1: Do not submit

This is based on an idea I presented on the mailing list. HOWEVER, I see no noticeable difference when attempting a commit in Eclipse, i.e. the part from selecting Commit in the Team menu, until the Commit dialog appears. 

Does anyone else notice an improvement? Even on the linux kernel with over 2000 files I saw no certain improvement. If there is an improvement it likely less than 10%, which is less than I expected.
