It means that something like this doesn't work:

#!/usr/bin/rdmd --shebang -I/asdasdasdasd/asdasdasdasd/asdasdasdasd
-I/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/


Is it possible to add a command line switch to read params from a simple
file?

For example:


main.d:
#!/usr/bin/rdmd --shebang --params ./rdmd-params.conf
void main() { }

rdmd-params.conf:
-I/asdasdasdasd/asdasdasdasd/asdasdasdasd
-I/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/

I think that's a shell limitation. I've long had the plan to experiment 
with it like this: if --shebang is the first argument, rdmd should just 
read the whole first line and exec() a shell with it. That would solve a 
variety of issues related to limitations and quoting quirks.
