Excellent.

So . is in scope. Neat.

Compare existing:

$ hg -R thg-stable par
changeset:   3536:cd50b769e235
branch:      stable
tag:         0.8.3

$ hg clone -r . thg-stable thg-stable-bug1234

Planned (faking output):

$ hg clone -u . thg-stable thg-stable-bug1235
updating to branch stable
297 files updated, 0 files merged, 0 files removed, 0 files unresolved

-U should gracefully and silently override -u without mercurial moaning
at it (or at least not moan by default, i.e. without --verbose).
