Paul Licameli 45a0ce1819 Bug2268: should be able to use " in Nyquist Prompt for Mac... 
... We need to un-correct the smart quote characters back to dumb quotes
before passing the input to the Lisp interpreter.

The smart quote correction is a consequence of the move to the MacOS 10.9 SDK.
Stopping the correction at the source would require objective-C hacks in a
custom build of wxWidgets, and just not worth the effort.

This fix only corrects the text input at one wxTextCtrl.  Should we reexamine
other uses of that class?
