Unless NO-BRACKETED-PASTE, bracketed paste control sequences are used.

DONT-CLEAR determines whether a C-a + backspace character is sent (to
ensure that we are in the basic REPL mode, at the beginning of the line).

Valid values are:

1. NIL or T determines its behavior directly,

2. 'NO-NEWLINE will copy it from NO-NEWLINE after it has been
determined as above. This is the default, with the rationale
that when a newline is not sent, the user may want to edit
the expression before evaluation.
