widget: Simplify & document "translate"

This is a protected function. It doesn't need to return anything, as all
implementation just returned true, always. Also, the legacy API was just
a wrapper doing nothing special (except verify that we have a widget,
which the recursive code already does).

Tested with fr_FR :)

Ref T5363
