I don't know this code at all, but this change seems obviously ok to me.

I don't understand why the new gdb_test calls have an empty "message"
argument.

Actually, this code in gdb_test itself looks somewhat bogus.
Aside from parsing arguments by hand (why??), it uses a different
default for the message than gdb_test_multiple.  I don't understand when
this can ever be the right thing to do.

For your patch I suggest just leaving off the 3rd argument.

Also, when the second argument to gdb_test is the empty string ... I
suspect you actually want to use gdb_test_no_output.
