Re: [PATCH v4 2/7] i18n: unpack-trees: mark strings for translation

[Junio C Hamano <gitster@pobox.com>]

I think this patch is better than what is already in 'next', so let
me see if I can make it into an incremental update.

We'd need your sign-off, of course.

Subject: i18n: unpack-trees: avoid substituting only a verb in sentences

Instead of reusing the same set of message templates for checkout
and other actions and substituting the verb with "%s", prepare
separate message templates for each known action.  That would make
it easier for translation into languages where the same verb may
conjugate differently depending on the message we are giving.
