patch 9.1.1342: Shebang filetype detection can be improved
Problem: Shebang filetype detection can be improved
Solution: Improve detection logic (Eisuke Kawashima)
Vim does not correctly detect filetype from
- `#!/usr/bin/env --split-string=awk -f`
- `#!/usr/bin/env -S -i awk -f`
- `#!/usr/bin/env -S VAR= awk -f`
So update the current detection logic to detect those cases.
