--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

It is documented, albeit too tersely.  I tried to improve it by 
installing the attached.
