[PATCH v5 14/16] i18n: send-email: mark string with interpolation for translation

[Vasco Almeida <vascomalmeida@sapo.pt>]

Mark warnings, errors and other messages that are interpolated for
translation.

We call sprintf() before calling die() and in few other circumstances in
order to replace the values on the placeholders.
