Function            getfilespec - get a DIR proper filespec

  Syntax              char *getfilespec(char *s);

  Prototype in        filehk.h

  Remarks             getfilespec parses a string pointed to by s for a
                      file name. Any drive and path information is
                      stripped from the string and the filename.ext is
                      expanded with wildcards, as DIR does internally
                      (i.e. c:tchk.lib has a filename.ext of tchk.lib amd
                      c:tchk. has a filenameext of tchk., but c:tchk has
                      a filename.ext of tchk.*). The original string s is
                      modified.

                      getfilespec() relies on parsefilename() to strip
                      any drive and path information from s. Thus, any
                      restrictions applying to parsefilename() also apply
                      to getfilespec().

  Return value        returns a pointer to s.
