...which means, they don't deal with ACLs at all.  They only see what's
given in the st_mode permission bits.  With this change, the group
permission bits now show that *somebody* has certain permissions on the
file, thus the group permissions indicate a too open access for ssh, if
somebody except you have write access to the file.

Downside: If you use inherited Windows permissions, you'll often have
the case that Administrators and/or SYSTEM have full access to your
files.  This in turn shows up as rwx group permissions now.  If you
can't change the permissions (company requirements, etc) the ssh key
file permission test will get annoying.

So it's probably a very nice change (thanks a lot for bringing this up!),
but it will probably have some negative side-effects for existing
installations.

Despite of what I'm outlining above, me too :)
