This seems to be telling me what tilde expansion is.

I am at this point looking for any documentation (not even from POSIX,
any shell or frankly any Unix utility will do) that says "HOME need not
be absolute, if not, here's how that is handled". So far all I see from
POSIX is that it doesn't say anything about whether HOME is absolute or
not.
