From 6271d77cb1ccfb7e4124593b4463446fe1188cda Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Fri, 27 Mar 2020 00:48:57 +0000 Subject: [PATCH] unpack-trees: split display_error_msgs() into two display_error_msgs() is never called to show messages of both ERROR_* and WARNING_* types at the same time; it is instead called multiple times, separately for each type. Since we want to display these types differently, make two slightly different versions of this function. A subsequent commit will further modify unpack_trees() and how it calls the new display_warning_msgs().
