[mew-int 2489] stunnel 4.23

[Kazu Yamamoto ( 山本和彦 )]

Hello,

stunnel 4.23 has been released. I have upgraded from 4.20 to 4.23.
Unfortunately, it appeared that Mew cannot work with stunnel 4.23 in
very special environment. 

The case is that the destination of SSL tunnel is "localhost". This is
rare. But if you are also using SSH tunnel by hand, you might specify
"localhost" to the destination.

I'm using Mac. "localhost" is associated with ::1 (IPv6) and 127.0.0.1
(IPv4). stunnel first tries to connect ::1. If fails, stunnel gives
up. (Of course, stunnel should try the next, 127.0.0.1.)

I committed workaround to CVS where Mew translates "localhost" to
127.0.0.1 in stunnel configration files. Note that the same logic
already exists in the *source* side. (See mew-ssl-localhost.)
