Junio C Hamano 627a8b8dcd core-tutorial: trim the section on Inspecting Changes
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.
