test-status: add test for removed-and-untracked state (BC)
In Mercurial 3.0, "hg status" can list the same file twice if it was removed
but still exists in working directory, i.e. removed by "hg forget":
$ hg status --rev 0 removed
R removed
? removed
But since 65cdc6bab91e, untracked state, "?", is no longer displayed in this
example.
I think the new behavior is correct since a file should have single state, but
if it is a bug, this patch should be dropped.
$ echo "[extensions]" >> $HGRCPATH
$ echo "mq=" >> $HGRCPATH
$ hg init
$ echo 'base' > base
$ hg ci -Ambase
adding base
$ hg qnew -mmqbase mqbase
$ hg qsave
$ hg qrestore 2
restoring status: hg patches saved state
