How do I abort/revert an uncommited merge with Sourcetree and Mercurial?

[rgreig]

I'm using source tree with a mercurial repository. If I make a merge and decide against before I've commited it, how do I roll back to the exact state I was in before I hit the merge button.

Reverting seems to change all the file contents back to a previous version but then wants to commit all those changes as a new version.

I've been working round this by binning the repo and cloning it again but surely there must be to just abandon uncommited changes?
