put_backslash - Puts a path separator at the end of a path if needed. Allegro game programming library.

       If  the  last character of the filename is not a `\', `/', `#' or a device separator (ie. `:' under DOS),
       this routine will concatenate either a `\' or `/' on to it (depending on the platform). Note: ignore  the
       function name, it's out of date.
