OpenBSD now enforcing no invalid NUL characters in shell scripts

Ah, indeed. Here are the first 16 bytes of one:

4d 5a 71 46 70 44 3d 27 0a 00 00 10 00 f8 00 00 |MZqFpD='........|

There are already nul bytes here, and there are a lot more before the single quote gets closed at offset 0x200.

And I can confirm a NUL in 11th byte of my hello.c a.out:

  >>> s[:11]
  b"MZqFpD='\n\n\x00"

Looking closer, I missed the content of "BIOS BOOT SECTOR".
