'*' is a valid filename character (if not, please cite the part of POSIX
that claims that).  AFAIK, the only invalid filename character is '/',
which is a directory separator.  The problem with /proc/registry is that
'/' is a valid value name character, so keys like
"HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\mounts v2\/usr/bin"
end up as "/proc/registry/HKEY_LOCAL_MACHINE/SOFTWARE/Cygnus\
Solutions/Cygwin/mounts\ v2'/usr/bin'", which any Cygwin program
(including bash) will choke on.

If there's a solution, it should probably have something in common with
managed mounts...
