[PATCHv2 1/9] revlist.c: introduce --left/right-only for unsymmetric picking

From

Message-ID
<60adf7d73e44126289a98dada60f9c335ffc84b0.1299499429.git.git@drmicha.warpmail.net>
In-Reply-To
<cover.1299499429.git.git@drmicha.warpmail.net>

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}...
