It's not quite that inefficient, but it needs around 2* the size of the 
largest version of the file, unless you're checking out HEAD.

Binary diff needs 3* at the moment, due to the way it works (it needs 
both full copies in memory to work out the diff, which may grow 
potentially to the original size).
