[TxMt] Fortran asterisk comments

[Stefan Duret]

Thanks for the reply, but I've already figured this one out.  The  
problem was that the asterisk was being recognized as the  
multiplication operator before being recognized as the beginning of a  
comment line.  The simple solution was therefore to move all parts of  
the language grammar describing comments above those parts describing  
mathematical operators.

Also, there is no need to escape the asterisk (or any other special  
character) when it is placed between square brackets.  Fortran 77 does  
not allow for whitespace before the asterisk either so there is no  
need for a \s*.
