I need to get only digits from mod_parts. Some plugin commands (e.g.
rspush in bzrtools) declared in modules inside packages (not in
__init__.py). If we simply collect tail of mod_parts as
'.'.join(modparts[2:]) then we get incorrect result:


D:\Bazaar\sandbox\bzr.dev.dot.wrong>python bzr help rspush
usage: bzr rspush [LOCATION]

(From plugin "bzrtools.rspush")

Upload this branch to another location using rsync.
...


I'm sure it will be wrong.

But if user unpack tar of 0.11 release of bzrtools and copy it to
plugins directory (e.g. ~/.bazaar/plugins/) then there is directory
called bzrtools-0.11.0 but in help it shown as "bzrtools-0". I think
it's also wrong.

Well, I make my changes primarily for help. And it seems that
Command.plugin_name() used only in help.

I could move my test to test_commands.py but I think that in
test_plugins.py it more appropriate. Also because there is already
exists similar test (based on which I wrote my test case). If you think
that I need to rework test to get +1 I'll certainly do it.
