I'm starting to think the way to go about this is to use a utility that
bypasses the kernel's VFAT file system and treats /dev/sdb1 as a block
device. A few have been suggested. Maybe a hex editor. Maybe
fsck.vfat. Maybe mtools, possibly modified since the documentation
https://www.gnu.org/software/mtools/manual/mtools.html#default-values
says:

    Subdirectory names can use either the ’/’ or ’\’ separator.

and that's just how I *don't* want it to treat the '/' in the DOS name.

But maybe a neighbour's old Windows machine.

But the guy that gave me this sd card a few years ago happens to be
visiting me soon from out of town, so I'll show him what's up.
