[PATCH] update howto/using-topic-branches.txt
Various updates and cleanups for my howto on using branches in GIT as a Linux subsystem maintainer. Three categories of changes: 1) Updates for new features in GIT 0.99.5 2) Changes to use "git fetch" rather than "git pull" to update local linus branch. 3) Cleanups suggested by Len Brown Signed-off-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Junio C Hamano <junkio@cox.net>

Here's something that I've been putting together on how I'm using
GIT as a Linux subsystem maintainer.
