Hello,
here's a patch against vc-bzr.el (diff taken against CVS-1.23 HEAD),
containing some misc fixes. Only slightly tested on 23.0.50.1 built
on Debian from CVS sources.
Short summary of changes:
- completed transition to new VC; `vc-bzr-state' uses the new
'removed, 'ignored and 'unregistered states.
- new customization option `vc-bzr-log-switches' (analogous to
`vc-bzr-diff-switches');
- bugfix in `vc-bzr-unregister': must not delete unregistered file;
- vc-bzr-command overrides only LC_MESSAGES, not the whole
locale setting;
Detailed changelog:
* Copyright and version headers update. Remove some outdated comments
through the whole file.
* (vc-bzr-program-args): Removed because unused.
* (vc-bzr-log-switches): New customization option.
* (vc-bzr-command): Use LC_MESSAGES=C instead of LC_ALL=C. No longer
use `vc-bzr-program-args'.
* (vc-bzr-revision-granularity): New function.
* (vc-bzr-status): Update regex to match latest Bzr output. Use new
'removed, 'ignored and 'unregistered states.
* (vc-bzr-init-revision): New function.
* (vc-bzr-unregister): Must not delete file.
* (vc-bzr-find-revision): New function.
* (vc-bzr-checkout): Argument `rev' is explicit revision only if it's
a non-empty string, otherwise take head revision.
* (vc-bzr-print-log): Pass `vc-bzr-log-switches' to "bzr log".
* (vc-bzr-diff): Simpler build of the revision spec string.
* (vc-annotate-convert-time, vc-bzr-annotate-difference): Removed:
compatibility hacks for Emacs21, not needed in Emacs 22.
* (vc-bzr-dir-state): Added code comments. Removed redundant statement.
* (vc-bzr-dired-state-info): Only provide custom strings for
overloaded VC state 'edited; otherwise fallback to
`vc-default-dired-state-info'.
