From 79a9312cc99f9c2f2949e1211c708896e6037f64 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 9 Nov 2011 11:33:55 -0800 Subject: [PATCH] commit-tree: update the command line parsing We have kept the original "git commit-tree -p ..." syntax forever, but "git commit-tree -p -p ... " would be more intuitive way to spell it. Dashed flags along with their arguments come first and then the "thing" argument after the flags.
