Okay, the double backslash works with emacs -Q on my system as well.
Back in my customizations, it looks like I had not rechecked by setting the ispell-personal-dictionary variable ... was still using the ispell-cmd-args approach unfortunately. So it looks like the latter is the issue, because everything works now per your suggested settings.
I had originally tried using ispell-personal-dictionary before turning to ispell-cmd-args and now believe that I may have failed to touch the .hunspell_en_US file first (a known quirk) while I was testing the double backslashes among other ways of specifying the file path.
So it's safe to close the bug now.

I'll try to find a place to mention this.

Doesn't happen here. Please show the exact settings you used. Was
that in "emacs -Q" or with your customizations? If the latter,
perhaps some of your customizations get in the way.
