Delete Auto Save Files doesn't always work

[Bielawski, Richard G.]

Delete Auto Save Files doesn't work right for ange-ftp files.

Both problems are fairly simple to recreate.  #2 causes me hardship.

(1)
After opening a remote file using ange-ftp make a change and wait for 
an auto-save to take place.  Then kill the buffer without saving. The 
documentation says the auto-save file will NOT be deleted but it IS.
I'm not bothered by this but I noticed it and so I'm reporting it.

(2)
After opening a remote file using ange-ftp make a change and wait for 
an auto-save to take place.  Then kill Emacs.  When it asks to save
the buffer first, answer No.  As documented, the auto-save file is NOT 
deleted.  So far so good.

Now restart Emacs and open the same file.  Note the warning about 
auto-save data.  Again, good.  Ignore it, make a change and wait for 
the file to auto-save.  Now save your change and close the file.
The auto-save file is NOT deleted and never will be hereafter.
The problem this causes is, because our host is dumb and can't respond
to MDTM, every time the file is open a warning occurs
your_file.src has auto save data; consider M-x recover-this-file
