/**
   Replaces the extension in \p buf of max.<br>
   size \p buflen with the extension in \p ext.<br>
   If there's no '.' in \p buf, \p ext is appended.<br>
   If \p ext is NULL, behaves as if it were an empty string ("").

   \b Example
   \code
   #include <FL/filename.H>
   [..]
   char buf[1024] = "/path/myfile.cxx";
   fl_filename_setext(buf, sizeof(buf), ".txt");      // buf[] becomes "/path/myfile.txt"
   \endcode

   \return buf itself for calling convenience.
