[Sez-created self-extracting archives look in the current directory only]

There are two ways for a self-extracting archive to know where to
find itself.

Under MS-DOS 3.x, it can look at the environment area, and find its own
pathname just beyond that area.

Under both MS-DOS 2.x and MS-DOS 3.x, it can get the value of PATH from
the environment, and search each directory in the list for itself.

Adding either of these to Sez-created archives would mean additional
overhead of perhaps a few hundred bytes.  It didn't seem worth it at
one time.  It could be added if people really need it.
