tests: demonstrate inconsistencies with dirty state in various commands

Not only is the output of these commands inconsistent with respect to each
other when a file is deleted, they are internally inconsistent depending upon
whether the deleted file is in the top level repo or a subrepo.  It seemed
easier to show the problems, rather than describe them.  The original goal was
to fix the summary command with respect to deleted files.  I haven't fixed any
of the other issues yet, in case anybody believes the current subrepo behavior
is correct.

I think a natural understanding of clean/dirty is that they are two opposite
values of a single binary repo state.  If `hg update --clean -r .` changes a
file, then naturally that repo was dirty, and `hg update --check` should have
blocked it.  Deleted files are special, in that they don't block a commit.  But
they make the filesystem content not the same as a clean checkout.
