Hello,

I ha= ve found a regression in the behavior of shell-command-on-region, though sp= ecifically 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 er= ror with any other utility).
2. Open emacs -Q.
3. S= elect 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.
&q= uot;.
4. Call `M-| par'.

You will ge= t this error on emacs master emacs -Q , but *not* on emacs 26.1:
=
=3D=3D=3D
ERROR in parse_header: buffer was &#= 39;;; This buffer is for te'
error: client: reader got error Success=
=3D=3D=3D

What's surprising is that I have= selected the whole 2 lines to be sent to par, but the error from par says:= =C2=A0

=C2=A0=C2=A0=C2=A0 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.

=

Can you please review if that change could have caused this regression?<= /div>

Thanks.

Hello,

I ha= ve found a regression in the behavior of shell-command-on-region, though sp= ecifically 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 er= ror with any other utility).
2. Open emacs -Q.
3. S= elect 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.
&q= uot;.
4. Call `M-| par'.

You will ge= t this error on emacs master emacs -Q , but *not* on emacs 26.1:
=
=3D=3D=3D
ERROR in parse_header: buffer was &#= 39;;; This buffer is for te'
error: client: reader got error Success=
=3D=3D=3D

What's surprising is that I have= selected the whole 2 lines to be sent to par, but the error from par says:= =C2=A0

=C2=A0=C2=A0=C2=A0 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.

=

Can you please review if that change could have caused this regression?<= /div>

Thanks.
