Re: v1.5.4 plans

Perhaps it would be even more readable to simply split the printing of
the commit message and the diff. Tracking this bug was a bit confusing.
Ideally, print_summary would just say:

  print_commit_message(commit);
  print_diff(commit, "^commit");

where obviously each of those takes a few lines to say properly. But the
use of a combination "show the log and maybe the diff" function seems
like a shell holdover, trying to avoid spawning too many processes.

Perhaps, but that's post 1.5.4.  There is no short-hand to call the
single commit diff-tree and not give any commit header afair.

Anyway, format-commit-message() makes it much more readable ;-)
