Hi!
Completion is very good, but very complex to quickly understand it :) So
far I've configured everything as compinstall was guiding and I'm
satisfied. Only one thing bothers me. I would like to get the list of
hosts not from /etc/hosts file but from some other file. Because then I
can rely on DNS to find the appropriate IP for given file name. And
names I can collect say in ~/.known_hosts one host per line. How can I
set it up?
(in fact ~/.ssh/known_hosts can be such file, but there the host name is
followed by lots of things on the line :)

You need to set the "hosts" style to the list of values in the file.
zstyle ':completion:*' hosts $(<~/.known_hosts)
should be good enough (host names don't need special quoting).

You can do that, too:
zstyle ':completion:*' hosts ${${(f)"$(<~/.ssh/known_hosts)"}%%[[:space:],]*}
This is using zsh's CompletelyImpenetrableExpansionSystem (TM):
"$(<~/.ssh/known_hosts)"
produces the contents of the file as a single string.
${(f)...}
splits that into an array of strings, one for each line of the file.
${...%%[[:space:],]*}
for each element of the array, strips off everything from the first
space or comma on, leaving the initial hostname in each case. (My
~/.ssh/known_hosts has IP addresses after a comma, which we don't want.)

Perfect. It works :) On the note of completion. I've noticed that now
when I say 'scp host:/path/files/* .' zsh complains that there were no
matches found. To work around this I had to put quotes around the
host:/path/files/*. I've tried to use
zstyle ':completion:*' preserve-prefix '(//[^/]##/|[^:/]##:)'
bur for some reason it didn't help. So I guess this style is not the
right one :) What would be the right action (beside putting it in
quotes?)

Thanks to Bart for this one. From my .zshrc file:
### SSH filename globbing:
if [[ $ZSH_VERSION > 4.2 ]]; then
autoload -U url-quote-magic
zle -N self-insert url-quote-magic
zstyle -e :urlglobber url-other-schema '[[ $words[1] == scp ]] &&
reply=("*") || reply=(http https ftp)'
fi
###
With the above magic, the * is automatically escaped as I type it. I
hope this is what you were looking for.
