I think it's intended for things like `zgrep'; currently, zgrep filters
grep's output with sed to do the same thing.  As far as I can see,
there's no particular problem with this -- since grep doesn't try to
open any files (gzip does), it never outputs an error message with a
filename, so there's no need to filter stderr (unless there's some error
I don't know about).  Other applications that report things like syntax
errors with the filename in the error message would need extra work to
work right.
