'help some-unknown-command' crashed as ListCmds wasn't checking if the command was actually found from the commands map. Signed-off-by: Jussi Maki <[email protected]>
Filter the commands shown by 'help' with a regexp instead of searching by name. This will become useful when there are many commands sharing the same prefix, for example StateDB has 11 commands and with this we can dump the help for all of them with 'help ^db'.

'help some-unknown-command' crashed as ListCmds wasn't checking if the command was actually found from the commands map.
While at it, make the 'help' a bit more useful by allowing filtering of commands with a regexp.
