Makefile: wrap hg.pot strings at 82 chars By default, xgettext will wrap strings at 79 characters. This width includes the two double-quotes and the '\n' added. Our strings are now wrapped at 78 characters and a line can therefore be up to 82 characters wide in the .po file. Setting the width to 82 characters ensures that xgettext does no silly wrapping on our already-wrapped strings while still wrapping long one-liners at 82 characters.
