From 3f9083cde3b434155c274168f166ffce2bb243e7 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Wed, 31 Mar 2010 21:22:06 +0200 Subject: [PATCH] merge: refactor code that calls "git merge-STRATEGY" In the try_merge_strategy() function, when the strategy is "recursive" or "subtree", the merge_recursive() function is called. Otherwise we launch a "git merge-STRATEGY" process. To make it possible to reuse code that launches a "git merge-STRATEGY" process, this patch refactors this code into a new try_merge_command() function.
