From 8cfe5f1cd5dabc3a21bc792327747deefeff6dff Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ren=C3=A9=20Scharfe?= Date: Thu, 2 Jul 2009 00:01:43 +0200 Subject: [PATCH] userdiff: add xdiff_clear_find_func() xdiff_set_find_func() is used to set user defined regular expressions for finding function signatures. Add xdiff_clear_find_func(), which frees the memory allocated by the former, making the API complete. Also, use the new function in diff.c (the only call site of xdiff_set_find_func()) to clean up after ourselves.
