(and never released) on the EMACS_23_1_RC branch. Namely reverse debugging and the display of STL
collections as watch expressions.
The long term aim is to move to GDB/MI, so these changes will be re-instated at some time in the future.
At the moment, however, there are issues with gdb-mi.el that have not yet
* vc-bzr.el (vc-bzr-after-dir-status): Add new argument. Return
file names relative to it.
(vc-bzr-dir-status, vc-bzr-dir-status-files): Pass the bzr root
relative directory to vc-bzr-after-dir-status.

"no matches" rather than "Can't find manpage", as the latter reads
like -k was interpreted as a page name, which is not so. (My
bug#5431.)
