Heinrich Schuchardt 6c74e94a65 lib/display_options: avoid illegal memory access ...

display_options_get_banner_priv() overwrites bytes before the start of the
buffer if the buffer size is less then 3. This case occurs in the Sandbox
when executing the `ut_print` command.

Correctly handle small buffer sizes. Adjust the print unit test to catch
when bytes before the buffer are overwritten.
