Fixed. Now you will be able to commit (and then get bug#3214).

Actually the problem only happens with removed directories (because
file-writable-p also returns non-nil if a file can be created).
Recipe:

mkdir /tmp/foo
cd /tmp/foo
bzr init
mkdir subdir
touch file subdir/subfile
bzr add
bzr commit -m "c1"
bzr remove subdir
echo 1 >> file
emacs -Q
M-x vc-dir RET
M
v

Isn't ctrl-g good enough for aborting, rather than introducing a 3-state
question?
