Death to "hg update -C"

[Jelle Herold]

Hello,

As much as I love mercurial, I *really hate* "update -C"...

This is the second time I lost work due to some confusion with
hg merge, hg revert and hg update '-C'.

(extra disastrous this time where 1. failed backups and
  2. I actually destroyed the work of a colleague).

So, I know the real bug is in front of the screen, touching
the keyboard. But IMHO mercurial should take extreme measures
never to loose any (outstanding) work.

Even if I say '-C', many times I don't mean it.
I suppose I'm not the only one?

Can this be fixed?

Regards,
Jelle.
