bug#34798: 27.0.50; xclip issue in tramp mode

[Ergus]

Hi:

There is an issue in xclip-mode when using tramp

emacs -q -nw
C-x C-f /ssh:user@host:file RET
M-x load-file RET xclip.el RET
M-x xclip-mode RET
abcd C-SPC C-a M-w C-e RET   <-1
C-y                          <-2
RET                          <-3
C-y M-y RET                  <-4
S-C-v                        <-5

Produces this output:
abcd                         <-1
sh: xclip: command not found <-2
                            <-3
abcd                         <-4
abcd                         <-5

As you can see the 2) yanks the error message including a new line.
But 4) (emacs yank + yank-pop) yanks the text and 5 (xterm-paste) too.

Best,
Ergus
