[poky] Git commit messages

[Darren Hart]

Just a reminder to folks. Please remember to line wrap your git commit 
messages at 80 chars or less. Aside from make the pull requests easier 
to consume on mailing lists, extra long lines don't work well with "git 
log" as it doesn't re-wrap them, it just truncates the lines.

Thanks,
