It's not an error, it's actually a bugfix. As you can see, the message
is a "warning", not a "fatal", which means it does not stop the
program from running. It has always been intended this way.
If you want to enforce a minimal number of arguments and exit if
that number is not reached, you have to do it from inside the script
with something like "if { test $# -ge 1 }".
That said, it's probably useful functionality for the execlineb
binary to have, so I'll consider having a switch implementing it
for a future version.
