----------------------------------------
I have found a few bugs in OptionParser's accept feature:

Hexadecimal and binary numbers are not properly supported for Integer

OptionParser::DecimalInteger, OptionParser::OctalInteger and OptionParser::DecimalNumeric convert invalid input to 0 or nil instead of raising InvalidArgument.

The attached patch fixes the validation regular expression for handling binary and hexadecimal arguments and adds verification for DecimalInteger, OctalInteger and DecimalNumeric
