Extraneous output on Wayland for paste() from an empty clipboard

[melwyncarlo]

On Linux (Ubuntu) Wayland display system, when the pyperclip.paste() function is called and when the clipboard is empty, a message is printed on the screen: Nothing is copied

This comes from either of the two code statements:

1. https://github.com/bugaevc/wl-clipboard/blob/aaa927ee7f7d91bcc25a3b68f60d01005d3b0f7f/src/wl-paste.c#L267

            bail("Nothing is copied");

2. https://github.com/bugaevc/wl-clipboard/blob/aaa927ee7f7d91bcc25a3b68f60d01005d3b0f7f/src/wl-paste.c#L227

        bail("Nothing is copied");

The bail() macro function is defined in https://github.com/bugaevc/wl-clipboard/blob/aaa927ee7f7d91bcc25a3b68f60d01005d3b0f7f/src/util/misc.h#L25 as:

#define bail(message) do { fprintf(stderr, message "\n"); exit(1); } while (0)

I tried the following, but to no avail:

import os
import contextlib
with contexlib.redirect_stdout(open(os.devnull, "w")) and contexlib.redirect_stderr(open(os.devnull, "w")):
    ...

I believe this is because the printing is done from an external program.
This can however be suppressed by redirecting stderr to an anonymous pipe, just as it was done for stdout.
