listener: support multi-line expressions in plain mode.

* linenoise/linenoise.c (linenoise): If we are in
noninteractive mode, then do not just read one line and return
it. If an enter_callback is defined then keep accumulating
lines while the callback indicates incomplete syntax, until
EOF occurs or the syntax appears complete. Return the lines
glued together, with \n characters replaced by \r, so the line
is correctly entered into the history, and the trailing LF
obliterated, as usual.

* txr.1: Documented new multi-line behavior of plain mode.
