Subject: [PATCH] fixupdiff: escape ^ caret
Since commit: commit 1e30753d53d222fbe955f0643583d756105d557e Author: Jan Kiszka <jan.kiszka@siemens.com> Date: Fri Oct 11 13:43:41 2019 +0200 Fix ^= in example code Trying to escaping ^ here only leaves the backslash in the output. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com> we have plain ^ inside listing. Escape it with \ but only if not already escaped (as output of diff with old source will be). Signed-off-by: Michael S.
