Summary

This patch adds a new enum 'cmdtype' which will tell about the type of the
command that whether it's a read only command, it's recoverable write command or
an unrecoverable write command.

This will be used in deciding which level of hidden access a command can has.

I'm holding off on accepting this because I'd like to see an example before it is committed.

Since Python 2 doesn't have real enums and Mercurial tends to shy away from object-oriented programming, I'm -0 on the use of a class here. Module-level variables with a common prefix would accomplish the same thing.

I think the name could be better, but that can be bikeshed. Stamping my approval for the concept and pattern.

cmdtype might be overly vague, since I could imagine a number of classifications it could mean. Maybe "cmdwritetype"?

To make it less controversial, I would move these constants to registrar.command
class and rename them to lowercaseconstants. The registrar provides semi-public
API, which should be consistently named.

I think this should be folded to the other registrar patch, and sent with the patches
which actually change the behavior depending on the cmdtype value. So marked as
change requested.
