[COGITO PATCH] Improvements for cg and cg-help

[Pavel Roskin <proski@gnu.org>]

Hello!

cg should not run cg-help with arguments unless they were specified
after an explicit "help" command
("cg help -option")

cg without arguments should run cg-help.
cg with any option before the command ("cg -foo cmd") should also run
cg-help.

cg-help should print help for cg-help if specific help is not available,
e.g.:

$ cg-help foo
Error: no help available for "foo"
Usage: cg-help [COMMAND]
...
