Dear Sirs,
when I set

   openin_any = p

then fmtutil can't create any LuaTeX-based format files anymore:


   $ fmtutil --sys --all

   [...stuff omitted...]

Only LuaTeX-based formats are concerned, all other format files are
built successfully.

Everything works as expected with

   openin_any = a

and

   openin_any = r

I'm using the latest stuff in tlpretest.
