My ls is the /bin/ls that comes with Red Hat Enterprise Linux 6.3. But sure,
whatnow has no way knowing what the 'ls' in the user's $PATH might do.
I don't know that whatnow's attach ever gave me a blank Nmh-Attachment header.
What you are probably referring to was my request that send silently remove any
such headers. I asked for that so that users could put them in their templates
to
be filled in, or left blank at composition time.
