From 8af96e7c660d4c7fe0a43c8a7b9cfbdd5eeb1517 Mon Sep 17 00:00:00 2001

Subject: - don't append the extension if it's already there (PR 5076). - show
 magic branches in rlog (thanks for that nicer hack niall). - correct output
 in rcsdiff, so we perfectly match gnu's

all these bugs were found by sturm@ while he was using cvsweb
(which uses the RCS tools).
