Then what?

First, zsh does not complete to such executable files, so that's
a wrong reason. Moreover such executable files cannot be executed
anyway, because they are not in the path!

And if the current directory happens to be $HOME, zsh does not
propose blah-hdir/ in the completions.

It seems the reason is that the directory (and possible subdirectories)
is a candidate for the autocd. But my point is that such a directory is
not a command ('commands' was specified first in tag-order).

Both the "cdpath=(. ~)" and "setopt AUTO_CD" are necessary to make
this (IMHO incorrect) behavior appear. Otherwise blah-hdir/ is not
proposed as a completion.
