I expect this is a case of "you're holding it wrong", but I figure it's
worth asking what the right way to do this is...

I want to glob the equivalent of */*/somefile (not **/foo, specifically two
directories deep).

However, I do NOT want the glob to match if any of the directory components
are a symlink.

*(/) is the glob specifier for directories [1]

It would then follow that *(/)/*(/)/somefile would match dir/dir/somefile
and not dir/link/somefile.

This is not the case -- even *(/)/ (i.e. appending a trailing slash to all
directories) do not work out-of-the-box as one might expect.

I've read through 14.8 Filename Generation [2] as best I can (my favorite
hack being the NTREF=reffile bit) but haven't found anything that suggests
how one might do this.
