It is NOT a problem; this is exactly what the shell function is supposed
to do.  The stdout of the command invoked is used as the expanded value
of the shell function.  No part of stdout is actually printed to stdout.

The shell function is essentially a make implementation of the POSIX
shell `` (backticks) function.
