You are correct, and my subject line is miss-leading.  It is possible to
hit this code from cli gdb, but I believe this only happens if we fail
to open the file.

 - we first test "ui_out_test_flags (uiout, ui_source_list)" which I
believe is always true for cli gdb.  I couldn't see a way this can be
turned off, but maybe I missed something.
 - we then try to open the file in question.

If we're not printing source (mi) or the open failed (mi/cli) then we'll
pass through the code I changed.

Thanks,

Andrew
