It's the foldingStartMarker and foldingStopMarker (for each language  
grammar in the bundle editor). These are regular expressions matched  
against each line, and those lines which match one (but not both) of  
them, becomes a start or stop marker.

One caveat being that start and stop markers must have the same  
indent to be foldable.

So for Ruby comments you'd have to make up some convention, like  
using + on first comment line and - on last, e.g.:

     #+
     #  This is a comment block
     #  which automatically folds
     #-

Which would be foldable by using these patterns:

     foldingStartMarker = '#\+';
     foldingStopMarker = '#-';
