Added missing builtins; a few other clean-ups.

- The first "alias" "Yes" should be "No**".
- Made "builtin echo command" consistent with csh and sh manpages.
- In group of 3 interactive commands, 2 used .Pa instead of .Ic.
- "Name" section now has "builtin" and "built-in" for better apropos.
- Added these builtins: !, %, ., :, @, {, }, local, return
