Missing trailing newline with git log --pretty=format

Missing trailing newline with git log --pretty=format

[Andreas Gruenbacher]

Hello,

with the latest version of git from right now (e986ceb):

While trying to get a reverse list of commit ids, I noticed that git log 
prints newlines between commits, but not at the end. This results in two 
joined lines with:

	$ git log --pretty=format:%h HEAD^^..HEAD | tac
	aab3b9a7d4e3a7
	e986ceb

Any chance of getting this fixed?

Thanks,
Andreas

Use tformat instead of format. Or better for a script use

	$ git rev-list HEAD^^..HEAD

But somehow --abbrev or --abbrev-commit don't work. Am I doing
something wrong?

Hmm ... didn't know that, thanks. Now I wonder why anyone would ever want 
format instead of tformat ;)

Much better, thanks.

If your payload is multi-line, you would want to see a separating empty
line in between entries, but not after the last one:

	$ command with --format
        The first line of first entry.
        The second line of first entry.
        ...
        The last line of first entry.

        The first line of second entry.
        ...
        ...
        The last line of last entry.
        $ notice there is no extra newline after that

That is what --format does.  One-line-per-entry is a special case.  You do
not want a "separating LF in between entries", but a "terminating LF after
each entry".  T in --tformat stands for this "terminating" aspect, as
opposed to the "separator" behaviour --format gives you.
