Re: Per-language clean trailing whitespace option?

I got the save routine wrong...

...
var prefNames = {"cleanLineEnds":null, "ensureFinalEOL":null};
for (var prefName in prefNames) {
     if (gprefs.getBooleanPref(prefName)) {
         gprefs.setBooleanPref(prefName, false);   // not "true"!
         ko.extensions.yamlPrefsToRestore[prefName] = true; // not "false"!
     }
}
