Yeah, I was actually thinking to myself when looking at that code, "Hey,
doesn't our popen() use sh -c?"
I look at this and I can't help thinking that's the wrong answer; getting
shell quoting is hard enough, but having to double-quote it? That just
seems like a mistake to me. Also, depending on "ls"output to get a list
of files seems like that's fraught with problems as well. I suspect that's
why Norm is getting a blank Nmh-Attachment header; there's a blank line
being output somewhere by his version of ls.
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.
