[PATCH] empty bodies are OK in list items

[PATCH] empty bodies are OK in list items

[Ingo Schwarze]

Hi,

here is a minor tweak:
For -hang, -ohang, -inset, -diag and -item lists,
empty bodies are OK, they do not even warrant a warning.

See e.g. OpenBSD options(4) "option NKMEMPAGES*" for a nice
example.

OK?

Yours,
  Ingo

Ingo,

ok kristaps@.

I think that Joerg also brought this up some time ago.
