SCRIPTS: git-show-backports: list new commits and how to review them with -L

The new "-L" option is convenient for quick backport sessions, but it
doesn't list the commit subjects nor the review command. Let's just add
these to ease backport sessions. However we don't do it in quiet mode
(-q) because the output is sometimes parsed by automatic backport
scripts.
