Hi. I'm not able to reproduce this:

$ screen --version
Screen version 4.07.00 (GNU) 02-Oct-19

$ xargs --version
xargs (GNU findutils) 4.6.0

hello.txt
world.txt
$ cat b | xargs grep foo
hello.txt:foo

Not sure why you see the error and I don't. My best suggestion is to report it
to the Cygwin list, address@hidden. The Cygwin findutils maintainer will see
it there, and the screen maintainer too (me). 

Please see the reporting guidelines at https://cygwin.com/problems.html. In
particular, be sure to attach the output of cygcheck -svr.

Eduardo is right that it looks like a findutils problem, but it's probably best
to see if it's anything Cygwin-specific before you send it upstream.

Good luck,
Andrew
