So to solve my porting problem for NaCl, would it be best if I just did a system check for NaCl, and if it is the current system, then clear the "init-file-user" string?

In my case, init-file-user is set to "user", but "~user" is not expanding properly

Btw, I'd like to reiterate something I already suggested near the
beginning: just error out if "-u USER" is used on DOS/Windows. I
think this should put all this issue to rest, and avoid unneeded
complexity, FAQs, etc.
