[Qemu-devel] [PATCH] qemu: reset buffer pointers after CR/LF

[Jim Paris]

If readline_handle_byte() is sent both a CR and LF, and
readline_start() is not called after the first CR, then the LF will
cause the same command to be executed a second time.  Fix this by
explicitly resetting the buffer pointers when it is processed.
