[PATCH v3 0/2] Add in-place editing support to git interpret-trailers

This patch series adds support for in-place editing to git interpret-trailers akin to sed -i, perl -i.

v2->v3:
 - Rephrase two error messages according to the suggestions by Matthieu Moy.

v1->v2:
 - Split patch to make review easier, as suggested by Matthieu Moy.
 - Rename FILE * function parameters to a more readable name, as suggested by
   Matthieu Moy.
 - Write output to temporary file and rename after successfully written in full
   to avoid losing the original file in case of an error/interrupt. Pointed out
   by Eric Sunshine.

Tobias Klauser (2):
  trailer: use fprintf instead of printf
  interpret-trailers: add option for in-place editing
