The easiest way I found to emulate git cherry-pick (which does exactly
what you want) with hg is to use import/export commands:
It is indeed quite a pain to use in my experience, because you cannot
easily refer to the original commit the cherry pick is coming from
(i.e. no equivalent to git cherry-pick -x), and the conflict
resolution is quite dumb. One alternative is to be careful about where
you apply your patch
but that's not very convenient either.
