I believe that gdb-tui mode uses readline's callback interface.  It
should not make a difference, since the readline tty code makes sure
to turn off the bits (INLCR and ICRNL) that map carriage return to
newline and vice versa on input, but maybe that is it.  That is the
only reason I can think of for it differing between gdb-tui and other
readline-using applications.
