From 07924d4d50e5304fb53eb60aaba8aef31d4c4e5e Mon Sep 17 00:00:00 2001 From: Michal Privoznik Date: Wed, 16 Jan 2013 08:51:58 +0100 Subject: diff: Introduce --diff-algorithm command line option Since command line options have higher priority than config file variables and taking previous commit into account, we need a way how to specify myers algorithm on command line. However, inventing `--myers` is not the right answer. We need far more general option, and that is `--diff-algorithm`.
