Bug #8865: OptionParser acceptable bugs
https://bugs.ruby-lang.org/issues/8865#change-41625

Author: drbrain (Eric Hodel)

Target version: 
ruby -v: -
Backport: 1.9.3: REQUIRED, 2.0.0: REQUIRED


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
