bug#28075: 26.0.50; documentation: ange-ftp-lovers mailinglist not reachable

[Gregor Zattler]

Dear emacs developers,

the file lisp/net/ange-ftp.el contains references to the
ange-ftp-lovers mailinglist.  However it is not possible (for me
at least) to subscribe to the mailinglist via the address given in
this file: ange-ftp-lovers-request@hplb.hpl.hp.com.

Searching the web I also found the address
ange-ftp-lovers-request@anorman.hpl.hp.com but this too is not
reachable.

Perhaps the mailing list has vanished.  Please update the
commentary in said file perhaps by deleting tis misleading
information.

Thanks for emacs, Gregor
