Do you think that it would be better to list the letter list for each
keyword in repl_scanner.l or have something more generic? As not that
many commands are added in the replication protocol, I would think
that this is more than enough for each command, say:
[Ss][Ll][Oo][Tt]                { return K_SLOT; }
etc.

Indeed, good catch.
