[dev] [st] [PATCH 1/3] Add NUL character dealing

[Roberto E. Vargas Caballero]

NUL character is usually used as padding (basically  for timming purpouses),
and it should be ignorted. Some old telnet servers send it together each
character. It is also used in some terminfo entries (for example in xterm
terminfo entry).
