Below scripts files have executable bits.
But actually those are executed by ruby foo/bar.rb for example from Rakefile

I think If we want to run like this way, it is preferred not to have executable bits.
However if we want to execute like this way ./foo/bar.rb, we need to add shebang (#!/usr/bin/env ruby) [1]

lib/coderay/token_kinds.rb
test/functional/basic.rb
test/functional/examples.rb
test/functional/suite.rb

Could you merge it?
Thank you.
