Pardon me for coming in late, but what in the world has this to do with
the lexer's state at all?  IOW, I don't think I like either of what you're
suggesting ...

Patch v12 has them separated, if that was more to your liking. The stack state lived in MainLoop() and was passed into HandleSlashCommands with an extra state variable.
