[CMake] cmake locks when parsing a fortran file ending with a comment and not end-of-line

[lucatrv]

As the subject says, I found that cmake locks when parsing a file ending 
with a comment and without an end-of-line character. At least this happens 
with fortran files, but I suspect it could happen also with other languages 
(though I've not tested it).
However, I send enclosed a simple fortran code file which reproduce the bug.
Of course, under linux it is sufficient to open the file and resave it to 
correct the problem (then you can use diff to understand that the only 
difference is that the file was added with an end-of-line character).
However, under windows, many editors don't care of adding an end-of-line 
character at the end of edited files (and in particular MS visual studio 
doen't do), so many projects can have such files, and I think cmake should 
be able to parse them.
