Should we also filter out "other" from group_names(), so it is not listed
for "?"?
With this patch, "other" does not emit a warning when passed in as a script
command line argument.
If we filter "other" from group_names(), then the warning in "expert mode"
will be a bit confusing (group "other" not defined in documentation).

Also, it is not clear to me if this is intentional behavior that interactive
mode allows non-dcumented groups (with valid chars validation) and
expert mode does not allow non-documented groups?

It may be simpler to use the same helper in both modes (is_group_valid)
to emit the correct warning and either proceed (expert mode) or get
back to prompt (interactive mode).

Thanks,
Amir.
