Fix copy-pasting of CJK fullwidth characters.

Browse Source 
They are stored as two separate characters in the vtbuf, so copy-pasting
will cause them to be passed to terminal_input_char() twice. Extend
terminal_input_char() to explicitly discard characters with TF_CJK_RIGHT
set. This causes only the left part to generate input.
