[patch,fortran] PR32223 Backslash handling inconsistent

[Jerry DeLisle]

Hi,

Actually the backslash handling is quite consistent, however we did not include 
the '\0' case.

The following patch does this and I will commit to trunk as obvious with a 
ChangeLog after I finish regression testing.

Regards,

Jerry
