I just noted that darcs does it roughly this way too.

When you commit ("record", in the darcs terminology), you're prompted
for a "patch name" from the command line, and then, you're allowed to
enter a "long comment", which opens a text editor with this:

| <what you just entered as the patch name>
| Place the long patch description above the ***END OF DESCRIPTION***
| marker.
| The first line of this file will be the patch name.
| This patch contains the following changes:
| A ./foo

Note the comment telling me about the first line (bzr could have this too).

>> """summary line.

This is also Emacs' best practice.

Whether you call it --line or --summary will not make your old history
work with it. We already have --long, --short, and --line. I don't think
having 4 log formatters by default would be a good thing for bzr's
simplicity. If my proposal is adopted, then I think the current behavior
of --line should no longer be available in the core bzr. Perhaps move it
to bzrtools.

If you want to have a log formatter that don't use my proposal, you'll
probably not follow the convention. Then, when _I_ run bzr log on _your_
branches, I'll get crap output. In a distributed environment, you can't
do without a global convention, and nobody will use it if the tool does
not enforce it a little.

And I think we should take advantage of the pre-1.0 phase to set this
kind of things.
