unlinkpath: make empty directory removal optional (issue5901) (issue5826)
There are known cases where performing operations such as rebase from a
directory that is newly created can fail or at least lead to being in a
directory handle that no longer exists.
This is even reproducible by just doing something as simple as:
cd foo; hg rm *
The behavior is different if you use `hg addremove`, the directory is not
removed until we attempt to go back to the node after committing it:
cd foo; rm *; hg addremove; hg ci -m'bye foo'; hg co .^; hg co tip
