Matthias Margush 99c09daec3 Fix filetype detection
The -i flag on Mac OS means:
    ჻ man file | grep -i -- -i
    -i      If the file is a regular file, do not classify its contents.

The --mime-type option is (mostly) portable:
- Linux uses --mime-type
- macOS uses --mime-type
- FreeBSD uses --mime-type
- NetBSD uses --mime-type
- OpenBSD uses --mime-type and does not use the same implementation as everybody else
- Solaris does not support MIME types at all
