Update comment.rb

It looks like source.ruble/lib/comment.rb is missing some code.

Change line 218 from:
index = l.index(/\S/)

to:
index = @disable_indent ? 0 : l.index(/\S/)

Then in your language bundle (like ruby.ruble/bundle.rb or js.ruble/bundle.rb), in the block: 
env 'source.ruby' do |e|

add:
e['TM_COMMENT_DISABLE_INDENT'] = 'YES'

Personally, to avoid any problems with the wrong value being passed in for TM_COMMENT_DISABLE_INDENT, I would also change line 8 of source.ruble/lib/comment.rb from:
    @disable_indent = (disable_indent == 'YES')

to:
    @disable_indent = (disable_indent.downcase == 'yes')
