The 'min_args' and 'max_args' values were ignored whenever
an 'argument' value was not present as a child of the 'command'.
'argument' values are often specified as children of the 'option'
value when more than one 'option' is an argument.
This patchset counts the number of 'argument' values specified
under a 'command' regardless of the level at which it appears.
If there are any 'argument' values, the 'min_args' and 'max_args'
are used to generate validation code for the 'command'.
