I've a filter recipe that is supposed to drop the last part of the body.
Currently it's a q instruction in sed.
Now, what happens if a buffer boundary happens to occur during the unused
part, and procmail senses a write error? It hasn't happened yet, but it
might. I don't want to put the `i' flag on the recipe, because then any
other write errors, which I would care to know about, would be ignored.
Should I change the sed instruction from q to !d [or p with the -n option]
so that sed will accept the entire text? (Normally that is a suboptimal way
to write sed code.)
