This does not seems to be working:
```
$ irb
irb(main):001:0> require 'optparse'
irb(main):002:0> o = OptionParser.new
irb(main):003:0> o.on('-[a-z]') {}
irb(main):004:0> o.parse('-f')

```
Although it is not clear from the documentation, I'd expect that this should match every short option, but unfortunately, it does not work at all ...
