Thanks!
I've tested the feature and it works well. Very nice!

One thing that is sorely missing is a test case. Do you want to add one?

I'm uneasy with the above wording. Couldn't it be misunderstood as saying
that the second-to-last commit will not be picked? I think what is
potentially unclear is whether "final commit" and "final picked commit"
refer to the same commit or to two different commits.

Perhaps we could use 'combine' as a hint in addition to 'fold', for clarity:

  "This option is a quick equivalent to a histedit script which folds all
  commits, combining them all into one commit."

That would read clear enough and non-ambiguous to me.

The rest looks good to me.
