I believe it's dependent on the width of and/or number of lines in the 
listing.  When Oliver and PWS rearranged the NEWS file etc. into the top 
level directory, they eliminated the conditions necessary to reproduce it. 
It's rather tricky to construct by hand a listing that reproduces the 
effect; I haven't managed to do so.

This one I can reproduce as follows:

zsh -f
autoload -U compinit
compinit -D
zstyle ':completion:*' completer \
    _oldlist _expand _complete _match _ignored _approximate _prefix
zstyle ':completion:*' format '%SCompleting %U%d%u%s'

and then enter "egrefoo" and TAB twice on the "f", as described in 19587.

Interestingly, the display remains wrong even after ^R (redisplay).  This 
bug may be related to 19714, and both may, I suppose, be related to the 
use of %S/%s and %U/%u in the format string ...
