Instead, it should be 0x20 as in the other test in the commit above. This is supposed to NOT change anything as we handle interesting 20-0x20 asciis far before this if. So for sakeness, change to 0x20 (which is SPACE). Signed-off-by: Jiri Slaby (SUSE) Fixes: 7a99565f8732 ("vt: ignore csi sequences with intermediate characters.")
