Bug #12315: OptionParser parses quoted --dash strings in 2.3.0
https://bugs.ruby-lang.org/issues/12315

* Author: Petr Marek
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
Working on 2.2.4:

~~~
wmctile -c -x 'subl --new-window' --switch-to 'sublime_text.Sublime_text'
~~~

On 2.3.0, it fails:

~~~
wmctile -c -x 'subl --new-window' --switch-to 'sublime_text.Sublime_text'
wmctile/bin/wmctile:23:in `<main>': invalid option: --new-window (OptionParser::InvalidOption)
~~~

As seen above, even though the `--new-window` is a part of a string, OptionParser tries to handle it.
