tm_comment_blocks.rb

#!/usr/bin/env ruby
str = STDIN.read
out = ''
str.each_line do |line|
 		 if line[0] == 35
		  out << line
  		 elsif line[0] != 35
		  out << "#" + "\t" + line
		end
	  end

puts "#commentStart-12x12x4141l1" + "\n" + out + "\n" + "#commentEnd-12x12x4141l1" + "\n"

This should be added as a command in bundle editor.

commentStart-12x12x4141l1 -------- should be added to foldingStartMarker section in your ruby language bundle

commentEnd-12x12x4141l1 -------- should be added to foldingEndMarker section in your ruby language bundle

This will append and prepend the foldingStartMarker(i.e #commentStart) and foldingEndMarker(i.e. commentEnd) respectively to selected text. Which will allow folding in textmate. I'm going to work in some logic to get this to work on the entire document and make it toggle based on whether or not it finds the code after commentStart in the line, but this is pretty neat for cleaning up large comment blocks.

Awesome. Can't wait to see when you get farther on this.
