Patch Set 1: I would prefer that you didn't submit this

Somehow this doesn't work (or I look in the wrong place):
- modify a tracked file and save it
- "Compare With" > "HEAD revision" -> full SHA1 shown
- Select version in History View and "Compare with Working Tree" -> full SHA1 shown
- Select two versions in History View and "Compare with each other" -> full SHA1 shown

After the header line of your commit message there are 2 blank lines. One would be sufficient.
