        "Kill all proper subdirs of DIRNAME, excluding DIRNAME itself.

I think this behavior is rather error-prone and counterintuitive.
I would rather consider it a bug, and change it to exclude
DIRNAME even if it is specified in the syntactic form of a file name.

If this makes it hard to kill a subdir, we could add a new interface
for doing that, or we could make this command ask whether
to kill directory DIRNAME as well.  That would provide an accident-proof
way to ask for either behavior.
