censor: extract the part about writing the censored revision in a function

The v2_censor function is huge, now that its content has settled a bit it is a
good time to split individual part inside dedicated function. We start with a
small function that process the censored revision.

# A dummy extension that installs an hgweb command that throws an Exception.
