From 1719b5e446f54e4196903ae6ed5f8867a5755bf6 Mon Sep 17 00:00:00 2001 From: Miklos Vajna Date: Mon, 21 Jul 2008 18:10:47 +0200 Subject: builtin-merge: give a proper error message for invalid strategies in config 'git merge -s foobar' diagnosed invalid "foobar" strategy and errored out with a message, but foobar in pull.twohead or pull.octopus was just silently ignored. This makes invalid strategy both on the command line and in the configuration file to trigger the same error.
