By the way my mailer does:
? xv var HOME
#nodelete,import-environ-first,sync-environ,notempty:
set HOME=/home/steffen
(where xv temporarily enables *verbose* mode).
If i recall correctly you, once you were still taking part, have
been dissatisfied with TOCTOU issues for TMPDIR for which the same
holds:
? xv var TMPDIR
#default-value,import-environ-first,sync-environ,notempty:
set TMPDIR=/tmp
So i (fwiw) are in the camp
$ HOME= s-nail -R#
s-nail: Environment variable must not be empty: HOME
s-nail: There are messages in the error ring, manageable via `errors' command
#?0!0/NONE#ERROR|:/dev/null? var HOME
set HOME=/home/steffen
#?0!0/NONE#ERROR|:/dev/null? xit
