preprocess: Eliminate eval in subshell
This is part of the effort to improve performance by reducing the number
of command substitutions/subshells.

Under Bash 3.2.57(1)-release on a MacBook Pro with a 2.9GHz Intel Core
i5 CPU and 8GB 1867MHz DDR3 RAM, this shaves off O(0.15s) from the test
suite at the previous commit, but I anticipate this effect being
magnified on Windows platforms.
