That's not as easy as it sounds; that repo is 37GB (including data files 
not under version control) and we only have about 30GB of free space on 
that machine - and less during the night when the disk fills up with 
temporary files.
Then again, I don't suppose it matters whether we keep working on the 
master repo and investigate on a copy or vice-versa?

It does; just a few warnings (that I probably should fix!).

Nope.
