This is me pretending that I had noticed that the command was empty
and knowing that this was still OK :-). But once you mentioned it,
I knew I had already done something like that. See gdb.ada/bp_reset.exp:
gdb_run_cmd
gdb_test "" "Breakpoint $decimal, foo\\.nested_sub \\(\\).*"
Doing a quick grep, we have a number of occurences where we use
an empty command when calling gdb_test. And looking at gdb_test's
implementation, it just passes the first argument to gdb_test_multiple,
so it should indeed be equivalent. (phew, that was close! ;-)).
