Improve syntax detection based on shebang

Question

On a few occasion, I've seen code blocks such as:

#! /bin/zsh -

echo foo/*
echo this is not part of a C comment.

Being highlighted as C code even though the Q&A had a zsh tag and the shebang made it explicit what language the code is written in.

I feel like it should be relatively easy for the syntax highlighting code to detect this kind of situation and select the zsh syntax highlighter automatically here based on the shebang.

In any case, that's not limited to zsh, zsh just happens to be the language I use in most of my posts here. It would be useful for code blocks starting with #! /bin/bash - / #! /usr/bin/perl --, etc as well.

If the question is tagged zsh, it will already apply syntax highlighting 'shell style'. You can see that by checking the Tag Info; at the bottom there's a little message:

Code Language (used for syntax highlighting): lang-bsh

For the record, ♦ moderators are able to change this.

Stack Exchange highlighting isn't smart enough to parse shebangs, but we can help it by applying the correct tags to questions.
