1) a function which gets two arguments. [insert old description]
2) a buffer into which output gets inserted.
You should use set-process-buffer for that.
3) a file name for output.
Writing it directly into a file is somewhat ugly as an idea.
4) t to stop accepting output.
Why do we need that option? A filter function can easily discard the
data.
5) a list of filter/file descriptor associations.
The car's of the elements of this list are an item from 1)-4) as
above, while the cdr is a list of file ids for which this item is
supposed to apply.
That is very ugly. There has to be a better way.
Anyway, the hard part of separating stdin from stderr
is that they both come through the same channel in the pty.
