Summary0000123: In charmode the driver kills subsequent lines
DescriptionAfter an INPUT_CHARMODE input_to the deactivation of the charmode in set_noecho calls reset_input_buffer which basically sets .command_start to zero and so has to move the input_buffer accordingly. But it assumes that there is only input till .tn_end and copies only this part of the buffer (and sets .text_end accordingly).

If two or more lines were sent at once .tn_end just points to the end of the first line (where scanning for telnet negotiations has ended the last time), the real end is shown by .text_end. So reset_input_buffer discards everything after the first line.

The following patch fixes this for me:
