Subject: bug#57854: Test result to previous suggestion

In my previous message, I suggested that python might determine that some
input was given.

I have tested it now by letting the command print a message in case input
was determined,
and indeed, while the terminal still produces the error, using
`shell-command-to-string` now
returns the printed message. So I guess the 'hypothesis' was correct.
