commit --exclude misses deleted files

[Matthew Fuller]

When committing with --exclude'd files, commit takes no notice of removed files. Note that using `bzr rm` rather than `rm` appears to make no difference. Additional variant of exclude'ing a file that doesn't exist at all (e.g., 'c' in example below) also changes nothing.

Output ends:

+ /usr/local/bin/bzr --no-plugins --no-aliases stat
removed:
  b
+ /usr/local/bin/bzr --no-plugins --no-aliases ci -x a -m remove
Committing to: /tmp/bzr/t/A/
missing b
aborting commit write group: PointlessCommit(No changes to commit)
bzr: ERROR: No changes to commit. Use --unchanged to commit anyhow.

Repro script:

#!/bin/sh -x
bzr="/usr/local/bin/bzr --no-plugins --no-aliases"

${bzr} init A
(
 # Setup
 cd A ; \
 touch a b ; \
 ${bzr} add ; \
 ${bzr} ci -m add ; \

 # Remove b
 rm b ; \
 #${bzr} rm --force b ; \
 ${bzr} stat ; \

 # Commit everything but a (which has no changes anyway)
 ${bzr} ci -x a -m remove
 # Fails
)
