[ragel-users] ragel didn't rename data variable for C# code.

[Adrian Thurston]

Tracked as a feature request.

I'm not sure I will address this for 6.7, as it may require a 
pre-parsing pass and there are some sticky issues involved ... how to 
parse the host language to get to the ragel code where we specify the 
host language? Granted, only scanning is necessary, but it is still a 
problem.
