please add support for Jenkinsfile*, or other files with no extension using crunch bang syntax

When I write Jenkinsfiles by hand I use groovy, which I indicate in the Jenkinsfile on the firstline:

#!groovy

I also write script files in linux without dot extensions:

#!/bin/ruby

#!/bin/perl

#!/opt/python2.7/bin/python

et al… This is a long standing convention in *nix world, any ideas on implementing support for parsing the crunch bang line for syntax highlighting language choice? It could be any file without an extension, and not just Jenkinsfiles

You mean like a button or dropdown right in the diff header or something similar?

The issue that I see with it is that the extension syntax highlights diffs, not entire file contents. If the shebang is not part of the diff, it won’t be able to find it anywhere so nothing would be highlighted in that case. What do you think?
