Mercurial has an identically named feature: http://www.selenic.com/mercurial/hg.1.html#bundle

Quite useful at times.

It seems to do a subtly different thing by default, though: the git bundle makes a bundle out of the entire repository. The hg bundle bundles the commits that are 'not known to be in another repository'.

Yep, that's correct. It also differs in that you use "hg bundle" and "hg unbundle" instead of "git bundle create" and "git bundle unbundle"

If you want a one-shot archive of the entire repo, just specify -a or --all on the command line. Here's an example: http://pastie.org/1617081
