When I try to emulate this with CVS, I also need the additional space.
Right _you_ would have to have _one_ modified source tree in parallel if
_you_ would want to do this. These so called modern VCS force you to do
so. Also, with svn etc. you have the whole history bloating and
polluting your checkout (Now try recursively grepping a deep source-tree
with a long history. Try gcc's (svn) source-tree to experience what I am
referring to).
svn just keeps two copies around. working tree and pristine last checkout.
True distributed VCS keeps all history around. However, they also
typically keep the history in a compressed or other binary form so the
problem you have with recursive grep is not nearly so bad in those systems.
Also, some VCS's (for instance, bazaar) do differentiate between
repositories and working trees/branches and checkouts. So "bzr checkout
--lightweight" will get you a CVS-like checkout without history.
