Doesn't look like it, which is indeed an oversight.

The description is as given by the helptext:

Usage: $0 [-doFMz4][-i id] file c h s (max: 1024 256 63)
    -d    add DOSEMU header
    -o    print filesystem offset to stdout
    -F    format partition as FAT32
    -M    "c" argument is megabytes, calculate cylinders
    -z    use zipdisk geometry (h=64 s=32)
    -4    use partition entry 4 (standard for zipdisks)
    -i    specify the MBR ID
    -s    output a sparse file (don't allocate all blocks)

It is worth noting that it, like the "mtools" syslinux installer,
invokes mtools to do the actual formatting.
