Re: Redirecting standard output

[Lars Magne Ingebrigtsen]

I've spent a couple of hours reading the code in `call-process' in more
detail.  Man, that's a complicated function.  Thanks for the warning,
Eli.  :-)

Anyway, I think that redirecting STDOUT to a file would be very easy to
implement, and would be quite non-invasive.  (The code already has a
redirect-to-fd case, the /dev/null output, so there's very little code
to add.  Just open something else than /dev/null, and you're there,
almost.)

However, redirecting STDERR to a buffer seems like it would be quite
complicated, unfortunately.  I thought that having STDOUT and STDERR be
handled symmetrically would be a nice feature (for redirecting STDOUT to
one buffer and STDERR to another, for instance), but unless I'm reading
the code wrong (and I very well could be), I don't see an obvious way to
do that.

Does this assessment of the complexities involved seem accurate?
