The patch itself is okay, but all the stuff around the patch is a bit 
weird, such as:

1. all those email headers in the commit message
2. useless indentation in the commit message
3. subject line in commit message says "PATCH 2/2", but email subject 
line says "PATCH 1/2"
4. stray comma in email subject line
5. spaces before colon in subject lines

This is taking too long, so I'll post a cleaned-up version.
