add a script to diff rendered documentation
After making a change to the documentation, it's easy to forget to check the rendered version to make sure it was formatted as you intended. And simply doing a diff between the two built versions is less trivial than you might hope: - diffing the roff or html output isn't particularly readable; what we really care about is what the end user will see - you have to tweak a few build variables to avoid spurious differences (e.g., version numbers, build times) Let's provide a script that builds and installs the manpages for two commits, renders the results using "man", and diffs the result. Since this is time-consuming, we'll also do our best to avoid repeated work, keeping intermediate results between runs. Some of this could probably be made a little less ugly if we built support into Documentation/Makefile. But by relying only on "make install-man" working, this script should work for generating a diff between any two versions, whether they include this script or not.
