Subject: server/tun-slip.c: Treat ESC END as an error, and junk the packet.
X-Git-Tag: 1.0.0pre11~47
X-Git-Url: https://git.distorted.org.uk/~mdw/tripe/commitdiff_plain/c85c17123f9713266341520e86e0acb31fad4031

server/tun-slip.c: Treat ESC END as an error, and junk the packet.

The code already treats ESC ESC as an error, so this is for consistency.
