However, there should be a restriction on egg names when they are
installed into henrietta, to make sure that they are portable to all
operating systems.  The safe list is a-z, 0-9, !, #, $, %, &, ', (, ),
comma, -, ., ;, =, @, ^, _, `, {, }, and ~.  A-Z are safe if we make
sure that no two egg names differ only in case.  Personally I'd go with
a-z, A-Z (only used by 9ML-toolkit, F-operator, and miniML), 0-9, and
hyphen only.

There is also a blacklist of names that don't work on Windows and
should be rejected case-insensitively: con, prn, aux, clock$, nul,
com[0-9], lpt[0-9], ms$mouse, emmxxxx0, xmsxxxx0, smartaar, and setverxx.
This includes the globs (not regular expressions) con.* and *.con, etc.
