[PATCHv2] merge-recursive: add hint for translators in handle_change_delete()

[Ralf Thielow <ralf.thielow@gmail.com>]

The outputs in handle_change_delete() contain a lot of placeholders.
This could end up in confusion to translators. Add a hint for translators
that they can easily understand it without study the code.

The first version did only explain the first and the
fourth placeholder. Junio pointed out that the others
could still confuse translators. This second version
explains now all placeholders. It differs to Junio's
suggestion in a modified header and an optional part
for the other messages.
