[Qemu-devel] [PATCH] Docs: proto.md: Clarify NUL in export name

[Alex Bligh]

Clarify that

* The name is not NUL terminated (not just that the length
  'does not include NUL termination' which might be taken to mean
  there is NUL termination but the length doesn't include it.

* The name cannot itself include embedded NUL characters (despite
  it not being NUL terminated).
