Thanks for the feedback, I re-sent the original patch with the extended tests.

I also added a patch to move calculation of the length out of 
ME_InsertTextFromCursor since I find the code flow easier to follow that way.
Now all checks are done before calling the function, and len always means 
length.
Not sure what you think about that idea though, so feel free to reject that.
