[dev] [st][PATCH] Fix definition of CONTROLC0

From: Roberto E. Vargas Caballero <k0ga_AT_shike2.com>

DEL character is not thecnically talking a C0 control character,
although it has some common properties with them, so it is useful
for us consider it as C0. Before this patch DEL (\177), was not
ignored as it ought to be.
