Documentation (mainly user-manual) patches

Please pull from the maint branch at

	git://linux-nfs.org/~bfields/git.git maint

This is mainly revisions of the patches posted a few days ago, which
were uncontraversial, so I won't resend them.  (They did need more
proofreading than usual, though--thanks to everyone who helped!)

One final patch wasn't included before, so I'll follow up with that.
