Browse Source

substituted for the placeholder (e.g. "%1$s[[date]], %1$s[[time]]).

Some english words have different translations, depending on
context. In these cases the original string is augmented by
context information (e.g. "To:[[as in 'From page x to page
y']]" and "To:[[as in 'From format x to format y']]". This
means that we need to filter out everything in double square
brackets at the end of the string, otherwise the user sees
bogus messages. If we are unable to honour the request we
just return what we got in.
