Jiri Slaby (SUSE) 52af9897e7 tty: vt: fix 20 vs 0x20 typo in EScsiignore 
[ Upstream commit 0e6a92f67c ]

The if (c >= 20 && c <= 0x3f) test added in commit 7a99565f87 is
wrong.  20 is DC4 in ascii and it makes no sense to consider that as the
bottom limit. 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).
