This is a documented backwards-to-ucbMail-feature.  In Mail, it is not
necessary to separate message numbers/metachars from command names; so
you can use "d11" to delete message 11.  Mush wants to be a little more
structured in its parsing, but also wants to maintain Mail compatibility.
So it inserts a space to the left of any digit-string or .*^$ it finds.

Breaking at numbers in the middle of a path like /user2/... is obviously
beyond the intent of this parsing.  Shutting it off following a `/' is
a fairly trivial change, which I will make a note to get into the next
release.  That doesn't help with "pop11".

HOWEVER, mush does handle quoted strings correctly, that is, it does
not break up words in quotes.  To run pop11, you need only use

    mush> 'pop11'

However part 2, mush does NOT break up the words after history (!* etc.)
expansion is done, so you can make a general fix:

    cmd pop 'pop\!*'

which pastes the 11 back against the word "pop":

    pop11 args --> (pop) (11) (args) --> (pop11) (args)
			 ^--- !* --^         ^-- !* --^

By "general fix," I mean it will also work for your home directory:

    cmd /user '/user\!*'

Hence it doesn't matter what the "tail" of the path is.  The /user will
only be broken out when followed by a digit, as in /user2/cogs; the cmd
expansion will not happen to /user/anything/else.
