How can I examine a changeset in mercurial without looking up its parent? In mercurial, what's the equivalent of
git show HEAD^
Git-show gives the changeset metadata and the diff as well.

You should also take a look at the parentrevspec extension to enable a more Git-like syntax for specifying revisions.

Your question has two parts. First, how to get the metadata and diff for a changeset all at once:
hg log --patch --rev tip
You can shorten the options:
hg log -pr tip
The second part of the question is how to say "the parent changeset of X" without looking it up. For that you can use the parentrevspec extension Martin mentioned.
Once you enable the extension you can do:
hg log -pr tip^
You could add an alias to your ~/.hgrc file if you don't want to retrain your fingers from git's command:
[alias]
show = log -pr
Then you could use:
hg show tip^

Without parentrevspec he could just do "-r -2" to get the changeset before tip, right?

Yes, that's true. That doesn't work for something like 'hg show mytag ^' though, right?

In general, for this case, `hg export` is preferred (it lists full commit message, etc.).

Preferred by who? If you want the full commit message you can add `--verbose`/`-v` to the log command. `log`'s output is much more human readable (the date and node/parent IDs are in a friendlier format) and it supports `--color`, unlike `export`.
