From 3813e69031d2df2702f50b9649fa2e40ea11e558 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 23 May 2011 16:30:14 -0400 Subject: [PATCH] refactor get_textconv to not require diff_filespec This function actually does two things: 1. Load the userdiff driver for the filespec. 2. Decide whether the driver has a textconv component, and initialize the textconv cache if applicable. Only part (1) requires the filespec object, and some callers may not have a filespec at all. So let's split them it into two functions, and put part (2) with the userdiff code, which is a better fit.
