Well, there is one way to prevent it:  before pushing, "hg update"
the source repo to a changeset that doesn't have a .hgsub file.
(000000000000 will do.)

That'd be pretty annoying for production use -- and it subverts
the whole point of subrepos -- but it works as an emergency
workaround.

Note that it's not enough to simply remove .hgsub and/or
.hgsubstate.  It's the working directory's parent cset that
matters, not the working copies of the files themselves.
