Title: Extend command group regexp

Adjust wrong nesting (remove extra blank from each line) in some tests.

Aaaaand...

Fix issue #631 (In `help` output: aliases are no longer grouped under
Aliases heading but under (other))

Forbid redefining a group of a command once it is initialized. Also, add
some unit tests, checking for that, so we won't miss this if it happens
next time.
