Returning ERR causes an unknown sequence error when pasting, and doesn't 
display the last pasted line, until a key is typed.

Attached patch also fixes pastes that include non-printable characters.

Pasting multiple lines in a search prompt would search for the first line and 
dump all remaining lines in the buffer. With bracketed paste, prompts ignore 
and beep when non-printable characters are pasted.

Pasting control codes and escape sequences in the buffer (and prompts) would 
execute them, which might be undesirable. With bracketed paste, it only allows 
tab, LF and CR into the buffer.

It might be possible to enable verbatim mode and paste anything into the buffer 
or prompts. Such as pasting text that contains tabs or binary data into the 
search prompt, or pasting binary data into the buffer. But prompts should 
always ignore LF and beep. Or maybe verbatim mode could be automatic when 
bracketed_paste is set. I haven't looked to see if either would be an easy task.

The only problem I can see is that it breaks automation by preventing someone 
from pasting sequences into the buffer that would perform a set of commands.
