Brian, I appreciate your maintainership of run-mailcap, but first
you take a long time to reply then you upload immediately without
waiting for feedback on your comments. You have a couple people
here interested in testing and providing feedback prior to
release...

So by strict RFC interpretation, a mailcap rule specifying
"copiousoutput" implies non-interactive output on stdout, however
a mailcap rule lacking "copiousoutput" does not strictly imply
the opposite.

Unfortunately this strict interpretation of the flag isn't
useful for a couple reasons:

1. there's no way for the mailcap rule to know the length of the
   output since it depends on the input.

2. the use of a pager depends on the size of the output compared
   to the size of the terminal, but the mailcap doesn't know the
   size of the terminal either.

This is probably why mutt deviates from strict RFC for the
"copiousoutput" flag, meaning that mutt uses the flag to find
rules that generate non-interactive stdout.

Thanks for trying to provide a solution. I understand the reasons
for your choices, but unfortunately the various changes you've
made fail to provide a method of achieving the result I want
(which depends on "copiousoutput") so I'll have to continue to
maintain my fork.
