linenoise: defensive null pointer check.
* linenoise/linenoise.c (move_cursor_multiline): If the npos
argument happens to be equal to the current position (the
operation is a null move), then no movement is generated. In
that case, no ab_append operation is called, and ab.b will
stay null; this null pointer then gets passed to
lino_os.puts_fn as the string to output, and that will blow
up. This situation hasn't actually been observed.
