Clarify some messages during commit:
- use "branch 'foo'" to distinguish from "branch merge".
- commit messags can be empty (to abort commits)
- Added value for editor message: Tell about HG: lines like CVS does.
prompt: kill matchflags
Python already lets one to embed RE flags directly in a regex, which
is a much nicer way to do things:
(?iLmsux)
(One or more letters from the set "i", "L", "m", "s", "u", "x".)
...
matchflags was introduced in
67afecb8d6cc, and the record extension is the only
user. I've killed matchflag, and adjusted record code appropriately.

There are some reference to a CVS_OPTIONS environment variable doing that but
it does not work on my system (cvs 1.11.20, macosx).
