[PATCH v2 0/2] make commit --verbose work with --no-status

When running git-commit`, --verbose appends a diff to the prepared message, while --no-status omits git-status output; thus, one would expect --verbose --no-status to give a commit message with a diff of the commit without git-status output.

However, this is not what happens - the prepared commit message body is empty, entirely. (Needless to say, no diff is appended.) This patch series attempts to make this work, as one would expect.

[PATCH 1/2] extract setting of wt_status.commitable flag out of wt_status_print_updated()

Currently, the wt_status.commitable flag is set only when we call wt_status_print(). * Extract this logic, so that we don't have to go through the git-status output code just to set the flag.

* In fact, it is not set when --short or --porcelain are used. This
  series does not attempt to fix the bug, though it should be trivial to
  do so with this patch. See 9cbcc2a (demonstrate git-commit --dry-run
  exit code behaviour, Feb 22 2014).
