"bzr touch" in nested directories

[Parth Malwankar]

bzr-touch doesn't seem to work in nested directories. I am
not sure if I am doing something wrong here or if this is
an enhancement request/bug.

Its does work if I do "bzr touch" at root.
Giving absolute / root relative path also doesn't seem to work.
