Subject: bug#34174: 27.0.50; Calling `par' via shell-command-on-region always errors out

Hello,
I have found a regression in the behavior of shell-command-on-region,
though specifically for a third party binary `par'. par can be obtained
from http://www.nicemice.net/par/.
How to reproduce the error:
1. Install par and put it in PATH (sorry, I cannot reproduce this error
with any other utility).
2. Open emacs -Q.
3. Select the two lines that show up by default in the scratch buffer: ";;
This buffer is for text that is not saved, and for Lisp evaluation.
;; To create a file, visit it with C-x C-f and enter text in its buffer.
".
4. Call `M-| par'.
You will get this error on emacs master emacs -Q , but *not* on emacs 26.1:
===
ERROR in parse_header: buffer was ';; This buffer is for te'
error: client: reader got error Success
===
What's surprising is that I have selected the whole 2 lines to be sent to
par, but the error from par says:
buffer was ';; This buffer is for te'
I cannot reproduce this error on 26.1.
I looked at the git revision history that affected shell-command-on-region
that affected in recent times, but I couldn't find any.
But I do see
https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=d1ec3a0a8e4d7d56ebc1e4fa743130b9974ac6a8
affecting callproc.c/call-process-region.
Can you please review if that change could have caused this regression?
Thanks.
