Add an option

	-Xclasses

to the javadoc command line.  That would cause javadoc 
change its behavior when it encounters "package" names
on the command line.  Those names would, under this
option, be considered to be class names rather than package
names.  Under that condition, it should not load the
class from source, but rather should load the class
from the class file.

This is required for rewriting javah and rmic.
