Yes, "echo ~[ccc]" works correctly.  I'm using zsh 5.3 so maybe there is some
difference there.  Perhaps there is some difference in options/modules/etc.  If
I cut my .zshrc down to a minimum:

autoload -Uz compinit
compinit

zstyle ':completion:*' verbose yes
zstyle ':completion:*' menu select=2
zstyle ':completion:*:messages' format '%d'
zstyle ':completion:*' group-name ''
zstyle ':completion:*' squeeze-slashes true

zstyle ':completion:*:descriptions' format "%UCompleting %d:%u"
zstyle ':completion:*:warnings' format "No matches for: %d"

(with the above zsh_directory_name() too of course), plain ~[whatever] works
but ~[whatever]/ will not complete paths.  Do you have anything non-standard
in your completion?
