Marina Zhurakhinskaya 703b21cef0 Don't use double quotes for things that don't need to be translated
This is our convention.

The only exceptions are double quotes for words in comments that give
them a special meaning (though beware that these quotes are not truly
necessary most of the time) and double quotes that need to be a part
of the output string.
