something strange with case insensitive matching

["Andrej Borsenkow" <Andrej.Borsenkow@mow.siemens.ru>]

This one correctly completes:

bor@itsrm2% sudo rm /t/sh/z/-2/f/B<TAB>
bor@itsrm2% sudo rm /tools/share/zsh/3.1.7-pre-2/functions/B
Completing file
Base/      Builtins/

but this one not

bor@itsrm2% sudo rm /t/sh/z/-2/f/b<TAB>
bor@itsrm2% sudo rm /t/sh/z/-2/f/b
Completing `arguments', `file', or `option'


Normally, case insensitive completion works

bor@itsrm2% zstyle -L
zstyle ':completion:*' completer _oldlist _complete _match
zstyle ':completion:*' format 'Completing %d'
zstyle ':completion:*' group-name ''
zstyle ':completion:*' insert-unambiguous true
zstyle ':completion:*' list-colors ''
zstyle ':completion:*' list-prompt '%SAt %p: Hit TAB for more, or the
character to insert%s'
zstyle ':completion:*' match-original both
zstyle ':completion:*' matcher-list '' 'm:{a-z}={A-Z}' 'r:|[._-]=*
r:|=*' 'r:|[.-]=** r:|=**'
zstyle ':completion:*' menu 'select=0'
zstyle ':completion:*' old-list _match
zstyle ':completion:*' verbose true
zstyle ':completion:*:*:configure:*' tag-order 'options:-with:with\
options options:-other:other\ options' 'options:-without:without\
options'
zstyle ':completion:*:options-with' ignored-patterns '^--with-*'
zstyle ':completion:*:options-without' ignored-patterns '^--without-*'
zstyle ':completion:*:options-other' ignored-patterns '--with(|out)-*'
