Extra empty line in source fragments

In case of a language that does not uses curly brackets to define blocks (such as Fortran) there was a newline character in the variable c and this was written in the "code fragment" buffer and subsequently written to the output resulting in and extra empty line on top. I languages using curly brackets this is later overwritten by the while loop searching for the open curly bracket.
