Yes, and a similar problem exists with logical and '.', integer and '+' and '-', 
and complex and '('.

We could pass the current character into eat_line, but I would have to modify 
code everywhere it is used. Another option would be to put c inside the dtp 
structure, and then test it in eat_line. That is also quite intrusive.

Since we have this same if block for all the different types I think i will just 
modify by using the same else if (c != '\n') in the specific places.

I will resubmit the patch with those cases.
