hgweb: be consistent with the background highlighting on closed branches (Issue2386) The coal and paper web themes will highlight closed branches as a visual cue to the user. This patch makes the other two themes constistent. For users with difficulty differentiating colors, it would be better to split out closed branches to a new table or optionally hide them.

mq: fix the deprecation comment for qsave & qrestore. Changeset bcf90e712dc3 deprecated qsave and qrestore. In the deprecating comment, users were referred to 'rebase --mq' which -- at the time the message was written -- didn't exist. Currently, on the default branch, rebase *does* take a '--mq' option, but it probably doesn't do what Dirkjan expected it to do when he wrote the message. In the original, deprecating commit, little context was provided as to why this change was made. Based on my recollection, concensus at the Paris Sprint in February 2010 was that one of the problems with MQ was that it exposed far too many commands. Notable among these were qsave & qrestore: very few core developers understood what they did and even fewer (none, IIRC) actually used them. However, they couldn't be removed; not only do the usual backwards compatibility reasons apply, but the hg book refers to them.
