[PATCH 0/3] Teach ref-filter API to correctly handle CRLF in messages

The ref-filter API does not correctly handle commit or tag messages that use CRLF as the line terminator. Such messages can be created with the--verbatim option of git commit and git tag, or by using git commit-tree directly.

This impacts the output of git branch -v, and git branch, git tag and git for-each-ref when used with a --format argument containing the atoms %(contents:subject) or %(contents:body).

The first patch in this series adds a new test library, t/lib-crlf-messages.sh, that contains functions to test this behaviour for commands using either the ref-filter or the pretty API to display messages.

The second patch fixes the bug in ref-filter.c and adds corresponding tests.

Finally, the third patch adds a test that checks the behaviour of git log in the presence of CRLF in messages, to prevent futur regressions.

Philippe Blain (3):
  t: add lib-crlf-messages.sh for messages containing CRLF
  ref-filter: teach the API to correctly handle CRLF
  log: add tests for messages containing CRLF to t4202
