On old versions of UNIX "" was the same as ".".
It still is, at least, under SunOS and BSD/OS.

POSIX has some specific things to say about "." v "" when it
comes to things like opendir. This is one reason behaviour
varies, and why things like

#if defined(posixlike_os)
        if(*bp==0)
                return(".");
        else
#endif
                return bp

Are so common.
