Enables shebang usage of nix shell. All arguments with `#! nix` get
added to the nix invocation. This implementation does NOT set any
additional arguments other than placing the script path itself as the
first argument such that the interpreter can utilize it.
Example below:
```
#!/usr/bin/env nix
#! nix shell --quiet
#! nix nixpkgs#bash
#! nix nixpkgs#shellcheck
#! nix nixpkgs#hello
#! nix --ignore-environment --command bash
# shellcheck shell=bash
set -eu
shellcheck "$0" || exit 1
function main {
hello
echo 0:"$0" 1:"$1" 2:"$2"
}
"$@"
```
fix: include programName usage
EDIT: For posterity I've changed shellwords to shellwords2 in order
not to interfere with other changes during a rebase.
shellwords2 is removed in a later commit. -- roberth
