I have a locally converted `HEAD' from CVS -> Mercurial which contains
all the history of the Emacs trunk, and is now at 138 MB:

  address@hidden:/home/keramida/hg/emacs/head$ du -skh .hg
  138M    .hg
  address@hidden:/home/keramida/hg/emacs/head$

This repository doesn't contain *all* the branches which have ever
existed for Emacs, but a pair of branches won't really bloat the history
above 200 MB easily.

Both Git and Mercurial are trying hard to store large histories in an
efficient manner.  They make different trade-offs, so some things will
invariably end up different, but there is a lot of cross-pollination
between the two systems, and that's usually a good thing :)

HTH,
