--text (-a) is documented to change only the output, not grep's exit status.
Yet, it does change the exit status here:

  $ printf "a\0b\n" | LC_ALL=C src/grep -la a.b; echo $?
  (standard input)
  0
  $ printf "a\0b\n" | LC_ALL=C src/grep -l  a.b; echo $?
  1

Thanks, Paul.  In which case I'm closing this issue, too.
