No. I fix the task.c:ChildEnv(), which was wrongly scans empty
environment with non-MS-DOS-style layout (only one empty ASCIIZ string). And
yes, currently ChildEnv() for empty environment uses MS-DOS layout. What you
have against?

Unfortunately, unlike INT25/26 this MS-DOS bug isn't documented, but
used in some programs (smartdrv, MFT).

This was based on observation of all available documentation.
Unfortunately, documented layout makes smartdrv broken.

"not pass empty environment" anyway mean "don't make availabel startup
path" (what makes FreeCOM and some other programs, like programs from Norton
Utilities, unhappy). Also, MS-DOS _passes_ empty environment, why we
shouldn't?
