Someone on IRC complained that the watch completion isn't very good
As far as i can tell it's pretty typical for people to quote the first operand
of the command only when it represents a shell command string (as in
`watch 'foo | grep bar'` — so i made it so that we choose between _cmdstring
and _normal depending on that quoting. Hopefully not too magic
