Hello Richard,

I think this is a difficult call. On the one hand, it makes sense to 
change the first letter in a string of enclosed letters. On the other 
hand, it doesn't make sense to change it if it's part of some 
punctuation (e.g. from as part of a list or some such).

So the alternatives are either to make this context-dependent or to just 
choose a solution and stick with it. My guess is that this is an edge 
case, so just picking the currently more popular solution and sticking 
with it may be best.

Regards,   Martin.
