Re: git rev-list formatting

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?

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?
