question from current darcs user

[Raphael Bauduin]

Hi,

I'm currently using Darcs, but am looking at Mercurial as I've had
some problems with big commits with Darcs.

One feature I really like in darcs is that when I record a patch
(equivalent to hg commit), it shows me every change that took place
and asks me if I want to record it.
So, for each change reported by hg diff, I get a question and I can
decide to not record some changes.

A very practical example is if you're debugging code, and add some
line of code specific to the debugging process. When you're done, you
"darcs record", but you just don't record the debugging code. After
that, a simple darcs revert removes all debugging lines you put in
there. There's no risk to forget one, and it's also very fast compare
to gor through the code and look for the remaining debugging code.

So, is this possible with Mercurial. If not, is there a possibility
that this gets implemented in the future?

Thanks in advance for your help.
