Help, minor bug in testsuite

[Michael Snyder]

OK, not sure what to do with this one.  The test in gdb.base/list.exp
says:

     # Try listsize of 0 which suppresses printing.

     set_listsize 0
     gdb_test "list 1" "" "listsize of 0 suppresses output"


However, the test only passes because "" is the same as ".*".
In fact, the output is NOT suppressed, and I can find nowhere
in the documentation that says it SHOULD be suppressed.

I'm not sure what to do with this test...
