New help messages. Added suggestion for unknown/ambiguous options.
The help messages shown when argument error were redesigned and less
verbose now. When unknown or ambiguous option is given, show
suggestions like "Did you mean...". Some constant values related to
levenstein distance are borrowed from git help.c.
