Can you point me to the citation for that please (I'm not doubting you,
just interested to read the wording, which I could not find).

I'm a bit disappointed to see that a relative HOME is now documented
in the Emacs manuals, since IMO it lends legitimacy to a questionable
usage. I don't see it mentioned in eg the bash manual.
I also don't see why it is in NEWS since it is described as
a bug fix, and those aren't normally mentioned.
