Thank you for your reply. I apologize for the misleading description
of the syntax of my command. I meant that I type '$ ssh xyz' where
'xyz' is the first few letters of one of my known hosts, and then I
press Tab. It should then complete the host name, right?
I am including below the output after '$ set -xv'. I have
'demons.hell.com,666.666.666.666' in ~/.ssh/known_hosts , and I then
type '$ ssh demons' and press tab. (Of course, I have modified my
actual host and directory names. Note also: 'demons.hell.com' is the
unique host name in the file that begins with 'demons'.)

By the way, I seem even to have trouble simply autocompleting the
filename '/home/David Hasselhoff/.ssh/known_hosts'. Here is some output:
-- Begin Clip --
$ cd /home/David\ Hasselhoff/.ssh/know+ local 'IFS=
' 'cur=/home/David\ Hasselhoff/.ssh/know' i j k
+ [[ /home/David\ Hasselhoff/.ssh/know == ?(\\)\$* ]]
+ '[' -z '' ']'
+ _filedir -d
+ local 'IFS=
' xspec
+ _expand
+ '[' '/home/David\ Hasselhoff/.ssh/know' '!=' '/home/David\
Hasselhoff/.ssh/know' ']'
+ [[ /home/David\ Hasselhoff/.ssh/know == \~*/* ]]
+ [[ /home/David\ Hasselhoff/.ssh/know == \~* ]]
+ '[' -d = -d ']'
+ COMPREPLY=([EMAIL PROTECTED]:-} $( compgen -d -- $cur ))
compgen -d -- $cur
++ compgen -d -- '/home/David\ Hasselhoff/.ssh/know'
+ return 0
+ return 0
-- End Clip --
I should also add that completion *does* work on known_hosts with scp.
Thanks,
Hans
