Evidently, because on Windows "????" matches file names that have 4
characters _or_less_.  You can see this with "dir ???" etc.

Btw, there's another subtlety in Windows globbing of wildcards: it
matches both the "normal" file names and their 8+3 aliases.
Therefore, "????????" (8 ? characters) will match every file without
an extension, and "????????.???" will match _all_ the files.  But
perhaps the most surprising consequence of this is something this guy
bumped into:
