[PATCH 0/5] Use skip_blank_lines() for more commit messages

These patches are on top of js/find-commit-subject-ignore-leading-blanks (whether you want to put them into the same topic branch before merging or put them into their own add-on topic branch does not really matter to me).

It occurred to me that there might be more code locations where finding the commit object's body is hand-rolled, and could benefit from using the skip_blank_lines() function to handle not-quite-standard but still-allowed objects from being processed correctly.

I found a couple of instances, and made them consistent with the pretty-printing machinery.

I made fine-grained commits to allow for dropping contentious patches more easily.

There are four more instances which I did *not* change:

- fast-export: I designed this command to be as faithful in exporting
  the commits as possible. As such, even non-standard commit objects
  should be kept as-are.

- fmt-merge-msg: when showing signed commit messages, it is better to
  show the commit messages verbatim rather than trimming them.

- when signing a commit, it is better to use the original commit message
  than a munged one.

- notes' messages are left alone. I do not know whether there might be
  an intentional use of leading blank lines, but I wanted to err on the
  safe side.

I also considered treating tag messages the same way, but tags are much more likely to be signed, and I did not want to risk munging the tag messages just before signing them.

Johannes Schindelin (5):
  commit -C: skip blank lines at the beginning of the message
  sequencer: use skip_blank_lines() to find the commit subject
  reset --hard: skip blank lines when reporting the commit subject
  commit -S: avoid invalid pointer with empty message
  Skip blank lines when matching <commit>^{/foo}
