Re: [RFC] Fixing gdb.base/completion.exp (PR testsuite/12649)

[Marek Polacek <mpolacek@redhat.com>]

Ok, here's a stab at the first part of this test.  What I tried to do
is to convert "send_gdb + sleep + gdb_expect" to gdb_test{,_multiple,no_output}.
Also some quick notes indicated by `XXX'.  Do you agree with it so far?
I've tried to preserve all the already existing tests.  Thanks.
