[PATCH v2 10/11] 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 must call sprintf() before calling die() and in few other
circumstances in order to interpolation take place.
