You can't simply by running grep. At the moment, there is no way to
decompress while running grep.

I'm sorry, I thought you were asking how you would attack an existing
problem with the new syntax, to which my reply was, use the old
syntax; but in fact you were addressing the implementation.

This is an interesting suggestion, not just because of performance
reasons, but because I was trying to interface at the library level,
while using a decompressor program directly would avoid having to do
API impedance matching.
