In Guile 3.0.9, 'system*' would no longer open /dev/null for file
descriptors 0, 1, and 2 when its 'current-input-port',
'current-output-port', or 'current-output-port' is not bound to a file
port. This patch reinstates that behavior.
Fixes <https://bugs.gnu.org/63024>.
* libguile/posix.c (piped_process): Open /dev/null to use as in/out/err
if the corresponding port is not backed by a file descriptor.
* test-suite/tests/posix.test ("system*")["https://bugs.gnu.org/63024"]:
New test.
* NEWS: Update.
