FTP

[Devon Sean McCullough]

If a binary FTP transfer is interrupted, it resumes in ascii,
thus corrupting the binary file.
I do not know if this bug still exists in the latest version
but it seems unusual enough that it might have escaped attention.

In GNU Emacs 20.4.1 (i386--freebsd, X toolkit)
 of Wed Mar  1 2000 on 
configured using `configure  --with-x-toolkit --with-pop --prefix=/usr/local 
i386--freebsd'

Here's the relevant excerpt from buffer *ftp anonymous@ftp5.freebsd.org*
