[syslinux] Label scope

[Miller, Shao]

Good day, Jeremy.

In regards to your question concerning the scope of LABEL labels: Please
use globally unique labels.  We can pretend that the "simple menu
system" is a superset of a "normal" Syslinux config-file, which doesn't
have menus.  At the CLI, a label is only going to do one thing.

Using config.c32 or [vesa]menu.c32 to load a different config-file [set]
is something like starting over, but that's different than using the
INCLUDE statement, as far as I know.
