revset: drop TODO comment about sorting issue of fullreposet The bootstrapping issue was addressed at the parsing phase and we expect that fullreposet.__and__() fully complies to the smartset API, in which 'self & other' should return a result set in self's order. See also 90455e7bf543.

revset: document wdir() as an experimental function Let's resurrect the docstring since our help module can detect the EXPERIMENTAL tag and display it only if -v is specified. This patch updates the test added by 015c0d1087a3 since wdir() is now documented.
