Synch 'help' command descriptions with man page descriptions.

Put 'setpid' description in correct place in COMMAND MODE
command list. i.e. in same order as ask_cmd() will parse
it.

Simplify ask_cmd() by displaying prompt in edit loop
rather than passing editlevel to ask_cmd().

No intentional functional change.
