1. Spliting strings inside the call to `gettext()` in javascript breaks the string extraction process, so the string should kept in one line.
2. Using escape string inside a string in `gettext()` may cause the extractor to misunderstand the escape string, so that it will escape this escape string.

So the time-consuming i18n_extract step can be skipped for situations that only the translated strings are modified while the source strings are still the same.
