No, @foo@ is evaluated when shell_command is evaluated. So it would
have it's " chopped before it was folded into shell_command,
resulting in a the following:

./configure CFLAGS=-g -O

which would be wrong.

I admit to not having looked closely at your patch; would it handle
this scenario properly?
