From 003b33a8ad686ee4a0d0b36635bfd6aba940b24a Mon Sep 17 00:00:00 2001 From: David Aguilar Date: Sun, 31 May 2009 01:35:52 -0700 Subject: diff: generate pretty filenames in prep_temp_blob() Naturally, prep_temp_blob() did not care about filenames. As a result, GIT_EXTERNAL_DIFF and textconv generated filenames such as ".diff_XXXXXX". This modifies prep_temp_blob() to generate user-friendly filenames when creating temporary files. Diffing "name.ext" now generates "XXXXXX_name.ext".
