Is it an issue at all? Did you test it?
The locate-egg/local procedure in setup-download.scm contains
various checks like whether the target directory exists and
actually is a directory. I'm pretty sure that crapload of
reserved names Windows has are mostly device aliases, which
means they're not directories. Hence, it will already DTRT.
If you managed to get a local copy of an egg with a particular name,
by definition it means that that name is allowed under your OS;
it doesn't make sense to check that against a blacklist (which
by definition will always be incomplete). Also, what if Redmond
decides to fix their OS and get rid of these reserved names?
We'd be stuck with their shitty legacy ~forever.
If you're saying a backslash should be disallowed just like
a regular slash, I think that's acceptable. Other than that,
we should disallow these egg names only if it's really a problem.

We don't know about that. But since henrietta is just another egg,
that's definitely a possibility. But again, if you managed to get
an egg with a funny name onto your system, henrietta should serve it
without complaining.

I might want to call it "hfs+". You never know what someone wants to
call their egg, so let's not unneccessary restrictions.
