Puts a path separator at the end of a path if needed. allegro game programming library.
#include <allegro.h>
void put_backslash(char *filename);
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 Note: ignore the function name, it's out of date.
