I took this one, thanks. (should have been patch 1)

reviewing this I also spotted that you are using '' as default value. 
this meaning that only single --rev option can be passed. For commands 
that can affect multiple revision, we use [] the default value, that 
lets the user specify multiple --rev options. The returned option is 
then a list.
