Please rollback all of that, i have only reported something that
seemed odd to me.  What i really need is instead

  if `git cat-file -e ${relbr}:NEWS 2>/dev/null`; then

and that is what i will end up with.
_But_, now that i am here again, "git help cat-file" says

  -e
      Suppress all output; instead exit with zero status if <object>
      exists and is a valid object.
and
  OUTPUT
...
    If -e is specified, no output.

But this is not what happens if "output" includes stderr:

  ?0[steffen@wales ]$ git cat-file -e HEAD:NEWS                                 
                                                               
  ?0[steffen@wales ]$ git cat-file -e HEAD:NEWSS                                
                                                                 
  fatal: Not a valid object name HEAD:NEWSS
  ?128[steffen@wales ]$ 

I would also not expect $?=128 as an counterpart to EXIT_SUCCESS=0
when performing a qualified "test" action, but EXIT_FAILURE=1 is
just an as-bad non-0 exit status code, anyway.  To me
EX_NOINPUT=66 obtrudes itself as the right status, but my own
projects don't adhere to this from a-z or not at all, so what i am
talking about?  I mean, some things take time and are eventually
and temporarily a bit odd, so what?  That is just how it is.  Even
Sparta declined some day, and then it crushed, iirc.

Thanks for git, just yesterday evening i did rebasing and cherry
picking and commit amending and garbage collection and it saved me
days of work, or, to be more exact, i never have been able to work
the way i would work before.  Really.
Ciao.
