One general question:

It looks to me that this one could have been written using a simple
gdb_test, since I don't see us using the output at all?

Same for this one?

In fact, starting from here, you suddendly started using gdb_test_multiple
even when there was only one regexp used. I'm probably missing someting...?
Is it something in the output that make it unsuitable for gdb_test?
