Back when the core tutorial was written, `log` and `whatchanged` were scripted Porcelains. In the "Inspecting Changes" section that talks about the plumbing commands in the diff family, it made sense to use `log` and `whatchanged` as good examples of the use of these plumbing commands, and because even these scripted Porcelains were novelty (there wasn't the new end-user tutorial written), it made some sense to illustrate uses of the `git log` (and `git whatchanged`) scripted Porcelain commands. But we no longer have scripted `log` and `whatchanged` to serve as examples, and this document is not where the end users learn what `git log` command is about. Stop at briefly mentioning the possibility of combining rev-list with diff-tree to build your own log, and leave the end-user documentation of `log` to the new tutorial and the user manual. Also resurrect the last version of `git-log`, `git-whatchanged`, and `git-show` to serve as examples to contrib/examples/ directory. While at it, remove 'whatchanged' from a list of sample commands that are affected by GIT_FLUSH environment variable. This is not meant to be an exhaustive list but as a list of typical ones, and an old command that is kept primarily for backward compatibility does not belong to it.
