# unclaimed name chooses the admin password. Aborting is strictly better --
# the existing password is left in place.

# one it prints its usage banner to STDOUT and exits 0, which would be captured

#
# -c does NOT cover PHP_INI_SCAN_DIR, though: a conf.d file enabling output
# buffering still gzips this capture. -d would cover it and so would -n, but
# this SAPI accepts NEITHER -- -n is listed in its own usage banner yet still
# prints that banner to stdout and exits 0, with or without -c. So no flag
# closes that case here, which is why the gate below is load-bearing rather
# than defence in depth. Do not remove it, and do not "fix" this with -n.
