[Nmh-workers] $editalt and -noatfile

[Oliver Kiddle]

My script for handling replies relies on the $editalt variable. This
broke recently and git bisect pointed me to commit 25581a94 which makes
-noatfile the default. I don't care too much for the @ file but need
$editalt.

Does -atfile have wider effects than merely disabling the @ file or
is there a bug that $editalt relies on the @ file?
