From 60adf7d73e44126289a98dada60f9c335ffc84b0 Mon Sep 17 00:00:00 2001 From: Michael J Gruber Date: Mon, 21 Feb 2011 17:09:11 +0100 Subject: [PATCH] revlist.c: introduce --left/right-only for unsymmetric picking 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}...
