Re: Making a patch: "git format-patch" does not produce the documented format

From: John Keeping <redacted>

git-format-patch(1) says:

        By default, the subject of a single patch is "[PATCH] " followed
        by the concatenation of lines from the commit message up to the
        first blank line (see the DISCUSSION section of git-commit(1)).

I think that accurately describes what you're seeing.  The referenced
DISCUSSION section describes how to write a commit message that is
formatted in a suitable way, with a short first subject line and then a
blank line before the body of the message.

Thanks for the confirmation.  I've figured out what is going wrong:
Documentation/SubmittingPatches says:

    The first line of the commit message should be a short description (50
    characters is the soft limit, see DISCUSSION in git-commit(1)), and
    should skip the full stop.

What it *doesn't* say is that the second line of the commit message
should be empty -- precisely so that git format-patch turns the first
line into the Subject: but does not merge the remainder of the commit
message (the "body") into the Subject: line.  Now that I know to look
for this, I can see that the commit messages in the Git repository
show this pattern.

I'm preparing some clarifications of SubmittingPatches to explain
things that a new person (e.g., me) would not know.  To fix this
issue, I am inserting:

    This first line should be a separate paragraph, that is, it should be
    followed by an empty line, which is then followed by the body of the
    commit message.
