What's in git.git (stable)

There are a few usability fixes to 'maint' after 1.5.3.3 but nothing worth doing 1.5.3.4 for yet.

On the 'master' front, handful topics that have been cooking in 'next' have been merged, to be part of 1.5.4. Notable are:

 * "git-remote rm"
 * "git-send-email --smtp-server-port"
 * "git-svn" futureproofing.

There are many changes cooking in 'next' that will graduate to 'master' real soon now. It would probably be a good idea to slow down and cut 1.5.4 early without aiming to have anything with huge user visible changes once that happens, because there are two rather big topics mostly about the implementation and not about user experience (other than performance gain of fetch in a repository with insane number of refs).
