unison and protocol breakage

[Kevin Ballard]

No, the solution here is to not do anything. Anybody using 2.13 needs  
to upgrade if they want to work with 2.27. We are not in the business  
of providing old port versions, and we *should not* be.

If you're using debian/stable, just install unison 2.27 yourself. IIRC  
the default location is $HOME/bin, so you don't need to do *any* work  
to install it besides download the source and build it. Presumably you  
have ocaml installed already.
