`hg rollback', then: `hg ci' again and this will now contain the new 
changes as well.

The only feature I miss in the above sequence is that the original 
commit message is lost, so you actually have to remember to do something 
like:
 hg tip --template '{desc}' > msg
before doing the rollback.

An `hg amend' extension automating the above would be handy (or maybe 
this could be grafted in the 'record' extension, as an --amend option?)
