[PATCH] (updated) Use the first line of commit message in "log --line"

[Matthieu Moy]

Here's the updated patch.

Regarding the "\n" escaping, my current decision is that it's not
worth the trouble. -m is very handy for one-line summary, but the
shell's multi-line edition or a real text editor is probably much
better for multi-line messages anyway.

I think it's ready for merging. We can consider adding a -s, --summary
option later if people ask for it.
