[issue3079] sys.exit() called from optparse - bad, bad, bad

[Phillip M. Feldman]

Phillip M. Feldman <pfeldman at verizon.net> added the comment:

The current behavior of optparse is contrary to how most of Python
works. optparse should throw a named exception that can be trapped and
identified by the calling program.  Doing a SystemExit is unacceptable.
 I can't believe that this is such a hard thing to fix.
