The existing "--cherry-pick" does not work with unsymmetric ranges
(A..B) for obvious reasons.
Introduce "--left-only" and "--right-only" which limit the output to
commits on the respective sides of a symmetric range (i.e. only "<"
resp. ">" commits as per "--left-right").
This is especially useful for things like
git log --cherry-pick --right-only @{u}...
which is much more flexible (and descriptive) than
git cherry @{u} | sed -ne 's/^+ //p'
and potentially more useful than
git log --cherry-pick @{u}...
