"bzr ignored" doesn't show ignored files in unversioned directories

Subdirectores below ./top such as ./top/mysubdir
are not shown by bzr ignored until bzr add.

It may not be regarded as a bug, but as a newcomer
it took me some time to figure out what was going on.

A solution would be some clarification in
bzr help ignored and upon bzr ignored list subdirs as pending,

output bzr ignored:
top ./top
--pending-- (use bzr add . to commit)
mysubdir ./top/mysubdir

here's a demonstation of this visual "bug".

#!/bin/sh
rm -rf a1234
mkdir a1234
cd a1234
bzr init
mkdir -p p/q/r
mkdir -p s/t
bzr ignore ./p/q/r
bzr ignore ./s
echo "###### bzr ignored #####"
bzr ignored
echo "only outputs ./s as ignored"
bzr add .
echo "adding p, adding p/q"
bzr ignored
echo "finally as expected"
