zsh-4.2.0-pre-4: problems with _remote_files

Hi!

I've been testing zsh-4.2.0-pre-4 for a while, along with Alexey Voinov.
We've noticed a few problems with _remote_files completion (ssh).

First, Alexey Voinov reports a problem (that I can't reproduce):

$ scp localhost:s<tab>
No matches for: `file' or `remote file'
$ scp altair:<tab>
remote file
RPM@      archive/  tmp/
$

I.e. it says "no matches" or "remote file" (which is not expected), and
the file list is incomplete.

Second, I've noticed that quoting is broken inside _remote_files:

$ cd
$ scp localhost:t<TAB>
tmp/
$ touch \'
$ scp localhost:t<TAB>
<BEEP>
$ rm -f \'
$ scp localhost:t<TAB>
tmp/
$

I believe there were no such problems with zsh-4.1.1.
So I am about to blame the following chunk.
Can't you explain, please?
And thanks,
