(the group of watchpoint commands, and the `reset' command).
NetBSD has sorted everything alphabetically, but I think we would have
too many commands for that if all commands were actually documented
here, so this commit moves towards alphabetical order in several sections:
- section for pure ddb (non-"show") commands. Now contains the watchpoint
commands and is mostly in "logical" order.
- section for pure ddb "show" commands
- similarly for auxilary commands. Most of these are currently missing
here.
