If we're going to clean this up, maybe we could switch to use
gdb_test_multiple, which would allow the use of $gdb_test_name, and
remove the need for send_gdb calls.

Something like the patch below?

Thanks,

    gdb/testsuite: fix list.exp test cases
    
    PR testsuite/7142 -- old enough to have been converted from Gnats --
    points out that test_list_filename_and_function in gdb.base/list.exp
    has "fails" that are unmatched with passes.  This patch cleans this up
    a little.
