When --fixes is used in bzr cmdline, diff email should indicate this

[Michael B. Trausch]

When a branch is pushed to LP that fixes a bug in LP, and LP sends out a diff email for that revision, it should indicate that a bug was fixed (and which one). For example:

revno: 51
committer: Michael B. Trausch <email address hidden>
branch nick: trunk
timestamp: Fri 2009-04-17 15:33:03 -0400
message:
  Complete signal handling to end cleanly and not leave apps unreachable.
modified:
  src/AllTray.vala
  src/Application.vala
  src/Process.vala
  vapi/stdc.vapi

This was commited with the following command line:

bzr ci --fixes lp:315707 -m 'Complete signal handling to end cleanly and not leave apps unreachable.'

The message should then read:

revno: 51
committer: Michael B. Trausch <email address hidden>
branch nick: trunk
fixed bug(s): 315707
timestamp: Fri 2009-04-17 15:33:03 -0400
message:
  Complete signal handling to end cleanly and not leave apps unreachable.
modified:
  src/AllTray.vala
  src/Application.vala
  src/Process.vala
  vapi/stdc.vapi

Or something similar, maybe:

fixed bug(s): 315707 in alltray

For multiple bugs being fixed in a single commit, they should be comma-separated:

fixed bug(s): 315707, 0

or:

fixed bug(s): 315707 in alltray, 0 in nothing

If the bug is in multiple projects, perhaps additional information would be useful.
