[PATCH v2 0/5] Small "git interpret-trailers" fixes

Here is a series to fix a few small bugs in "git interpret-trailers".

Patch 1/5 and patch 2/5 are independent from the last 3 patches, and can be applied to master.

Patches 3/5, 4/5 and 5/5 depend on this series by Junio:

        jc/conflict-hint (2014-10-28) 4 commits
          (merged to 'next' on 2014-10-29 at 693250f)

Changes since the previous version are:

* use "%.*s" instead of a strbuf, in patch 2/5

* add new find_trailer_end() function and a call to strbuf_release(),
  in patch 4/5

Thanks to Junio and Peff.
