Removes can be uncommitted

  $ hg ci -m 'modified b'
  $ hg rm b
  $ hg ci -m 'remove b'
  $ hg uncommit b
  note: keeping empty commit
  $ hg status
  R b

Uncommitting a directory won't run afoul of the checks that an explicit file
can be uncommitted.

  $ mkdir dir
  $ echo 1 > dir/file.txt
  $ hg ci -Aqm 'add file in directory'
  $ hg uncommit dir
  $ hg status
  A dir/file.txt

`uncommit <dir>` and `cd <dir> && uncommit .` behave the same...

  $ hg rollback -q --config ui.rollback=True
  $ echo 2 > dir/file2.txt
  $ hg ci -Aqm 'add file2 in directory'
  $ hg uncommit dir
  note: keeping empty commit
  $ hg status
  A dir/file2.txt

  $ hg rollback -q --config ui.rollback=True
  $ cd dir
  $ hg uncommit .
  note: keeping empty commit
  $ hg status
  A dir/file2.txt
  $ cd ..

... and errors out the same way when nothing can be uncommitted

  $ hg rollback -q --config ui.rollback=True
  $ mkdir emptydir
  $ hg uncommit emptydir
  abort: cannot uncommit "emptydir"
  (file was untracked in working directory parent)

  $ cd emptydir
  $ hg uncommit .
  abort: cannot uncommit "emptydir"
  (file was untracked in working directory parent)
  [255]
  $ hg status
  $ cd ..
