Here is an attempt at adding control-C support for \password. With
this patch, we pass sigint_interrupt_jmp and sigint_interrupt_enabled
all the way down to pg_get_line_append(), which is admittedly a bit
more complicated than I think would be ideal. I see a couple of other
calls to simple_prompt() (e.g., \prompt and \connect), and I think the
same infrastructure could be used for those as well. I'll send some
follow-up patches for those if this approach seems reasonable.
