[issue4640] optparse doesn’t disallow adding one-dash long options (“-option”)

I came across this bug report and was unable to reproduce the described behavior.  I wrote a few test cases demonstrating that the behavior is indeed correct.  It passes both against 2.5.2 (the version described in the report) and the lastest 2.7.

The relevant code is line 602 of optparse.py in the function Option._set_opt_strings().

I believe this bug can be closed.
