Warning: Shadowing local variables

[dannysmith]

I'm getting these warnings when I run of sync.

/Users/danny/.rbenv/versions/2.1.4/lib/ruby/gems/2.1.0/extensions/x86_64-darwin-14/2.1.0-static/rb-appscript-0.6.1/_appscript/terminology.rb:57: warning: assigned but unused variable - rev
/Users/danny/.rbenv/versions/2.1.4/lib/ruby/gems/2.1.0/gems/omnifocus-trello-1.1.1/lib/omnifocus/trello.rb:46: warning: shadowing outer local variable - board

I'll try to sort the last two when I get a minute. It should just be a variable name change.
