bug#35257: eshell and xclip

[Daniel Sockwell]

Thanks for all the great work on eshell!  I'm a big fan and using it as my
daily shell.

I recently ran into a minor issue, however.  I discovered that xclip
does not seem to work at all in eshell: the same commands that work fine
in a term buffer (or in external terminal emulators) have no effect in
eshell.  Further, the command does not provide an error message, it just
fails to set the system clipboard.

(This is my first time submitting an Emacs bug, but I am sure it won't be my
last—I plan to get more involved in the project soon.  Please let me know if
should do anything differently in future bug reports or if I can provide any
other information about this bug/help in any other way.  Thanks so much!)

Best regards,
Daniel Sockwell
