Fabian Homborg db63be7909 Add support for bracketed paste
This is a terminal feature where pastes will be "bracketed" in
\e\[200~ and \e\[201~.

It is more of a "security" measure (since particularly copying from a
browser can copy text different from what the user sees, which might
be malicious) than a performance optimization.

Work towards #967.
