I do the same in hg. I do `hg amend` all the time to keep adding changes to my commit. At the end I may selectively undo some changes with `hg uncommit --interactive` or `hg uncommit --all` and redo the whole thing piecemeal with `hg commit --interactive` in order to slowly split up my work into several commits. Evolve makes it really easy to keep (and ignore!) a meta-history of all of my editions, with a clear lineage of which new commit replaced which prior commit.
I may also rebase my work onto the latest head at the end (not to be confused with git HEAD).
And all of this with a very nice interface. It's always --interactive, not sometimes --patch and sometimes --interactive.
Mercurial was my first DCVS and I loved using it, but I only touched on the basic features. I stopped using it when I switched jobs and to become proficient with git. I'll have to give it another try with one of my side projects.
