That's why I asked for clarification of what "shell escape" is in the 
context of this discussion.

I can tell you from a sudo point of view, having vim et al. use 
:'<,'>!sort is considered a shell escape in that the authorized program 
(/path/to/)vim is executing a sub-process.  It is possible to allow use 
of vim while preventing it from calling external processes via sudo.

I agree that :'<,'>!sort isn't something like breaking out of something 
intended to contain you.
