something strange with delete-char-or-list

["Andrej Borsenkow" <Andrej.Borsenkow@xxxxxxxxxxxxxx>]

bor@itsrm2:~%> compconf -L
compconf correct_accept='2n'
compconf match_original='yes'
compconf completer='_oldlist:_complete:_match'
compconf dumpfile='/home/bor/.zcompdump'
compconf oldlist_list='_match'
compconf path_cursor='yes'
compconf match_insert='unambig'
compconf correct_prompt='correct to:'
bor@itsrm2:~%> ls /a/p/u/z/*^D
bor@itsrm2:~%> ls /a/p/u/z/*<TAB>
zip/     zmodem/  zsh/
bor@itsrm2:~%> ls
zip/     zmodem/  zsh/

??? Where is the command line?

And related question:

bor@itsrm2:~%> ls /a/p/u/z/*<TAB>
bor@itsrm2:~%> ls /archive/pub/unix/z/\*
zip/     zmodem/  zsh/

Is it intentional, that pattern after the first ambiguous component is
preserved? (Oh, yes, I like it!) Is it possible to output it "as is" then and
not quouted?
