Support Tcl scripts?

[qwertychouskie]

MacPorts Portfiles have this at the top of every file:

# -*- coding: utf-8; mode: tcl; tab-width: 4; indent-tabs-mode: nil; c-basic-offset: 4 -*- vim:fenc=utf-8:ft=tcl:et:sw=4:ts=4:sts=4

Other Tcl scripts may start with this line:

#!/usr/bin/tclsh

By detecting these manually, it would be possible to detect many (most?) Tcl scripts even without updating/re-training the ML model.
