x86/boot(8) now states:

  If the specified
  .Pa filename
  does not contain an embedded slash character, the boot loader will also
  try
  .Pa filename/kernel
  and
  .Pa filename/kernel.gz .

Is the emphasis on an *embedded* slash to be taken literally?  I.e. are
leading and trailing slashes considered embedded or not?  In the former
case, why specifically mention embedded and not just say "contains a slash
character?"

The code just checks if filename *contains* a slash.  I'm wondering what is
actually intended here.
