Dear Jan,
granted, I'm more of a Subversion user than a Bazaar user, but I think I'm
very much able to interpret what bzr is telling me. Maybe my sentence "I just
tried trunk r100830 and Jan's patch from the emacs-23 branch has made it into
the trunk" wasn't clear. I did NOT apply
r100830 to an older revision of the trunk, I compiled the trunk as it is/was
in r100830. If my interpretation of "bzr log --include-merges src/xmenu.c" as
well as an annotate operation on src/xmenu.c in Emacs is correct, your patch
IS in the trunk. It got there through Chong Yidong's merge in r100770.
