Also, is there a way to avoid the "commit <sha1>" line, print some
information that I specify in the format string, and show the whole
message as is (without wrapping or other tweaks)?

Looks like `git log' does something similar to what I want anyway,
which leads me to a related question -- it's not clear to me what are
the differences between `git rev-list', `git log', `git diff', and
`git show', since it looks like they can all be tweaked to produce
similar outputs.  Are they all the same with different outputs?  Is
there some description of them with the differences explained?

The rev-list man page lists all commands of that family, with rev-list
being the bare bones version, and log and friends being more "high
level". log and rev-list walk the revision tree, show does not. Most of
that can be changed through options. whatchanged is a special family
member...

diff is from a completely different family (see git help diff or git
help diffcore). It never walks, but compares revisions (or other things).

The log family never compares things, but can show a patch, i.e. the
difference to the ancestor(s).

Also related, it looks like `--abbrev-commit' has no effect on `git
rev-list', but does on `git log', even through it's documented in the
former's man page.  So it looks like either there are more
(undocumented?) differences, or maybe that's also a bug?

I consider this a bug. In fact, it has an effect, but not a visible one.
You would have to use --abbrev=7 or such.

A patch is upcoming.
