Globs are not ran after variable substitution by default.
To run filename generation (aka globs) after variable substitution, use
$~var.

Your example:

Can be rewritten as:

        pattern=git*
        for entry in $path
        do
            # Print all files in the path that match the pattern. 
            print $entry/$~pattern
        done
        
It can be simplified further as:

        pattern=git*
        print $path/$~pattern
