Presumably any non-zero exit status will do. The only thing needed for
a command to work with 'if' in a shell program is that it exit with 0
for success and non-zero for failure.

This also works with:

    bzr inventory FILENAME > /dev/null 2>&1

I agree that a command simpler than either of these would be good.
Perhaps 'bzr file-inventory' could grow a '--quiet' option to (similar
to 'grep --quiet') suppress output and error, leaving the exit status
alone to indicate success or failure.
