Using Qt translated texts causes adding them to app ts

[SeeLook]

Hi all!

When I'm using translations from qtbase file this way:
QApplication::translate("QShortcut", "Help")
or
QShortcut::tr(""Help")
All those texts go into myApp.ts files after invoke lupdate.

Is there any way to avoid that?
Or some method to remove such messages from ts file?

I think, the best way to achieve above is to make changes in lupdate.
So I forked it, added small changes and there it is:
https://github.com/SeeLook/lupdate

Then simply way to have *.ts file without some context of tr() or translate() is to call:

lupdate -skip-context QFileDialog,QMessageBox,QProgressDialog,QShortcut -recursive src -ts file.ts

Write me if You find this usable or any another way.

Another solution that not require hacking Qt is to alias QApplication::translate method:

inline QString myTr(const char* context, const char* key, const char* disambiguation = 0, int n = -1) {
  return QApplication::translate(context, key, disambiguation, n);
}

and then get translated text with:

myTr("QShortcut", "Help");

Such texts are invisible for lupdate.
