So does Aspell hang because it is in an infinite loop or is it just keep on
repromting?

There is nothing wrong with them. I do it to save space. Yes it
contains some ugly stuff but it is completely contained within the single
source file so I don't have to worry about it anywhere else. I will not
unless it causes a problem.

I believe that is the correct thing to do but I will have to see the patch
