Problem:    Ranges for arguments, buffers, tabs, etc. are not checked to
            be valid but limited to the maximum.  This can cause the
wrong
            thing to happen.
Solution:   Give an error for an invalid value. (Marcin Szamotulski)

Problem:    Using a range for window and buffer commands has a few
            problems.
            Cannot specify the type of range for a user command.
Solution:   Add the -addr argument for user commands.  Fix problems.
