Subversion internally stores differences (on the server as well as
transmission over the network) using vdelta and xdelta binary
differences. When you use diff or merge, a completely orthogonal
algorithm kicks in which can only be applied to texty files, meaning
that Subversion will - heuristically - try to determine textiness of
files before it uses those algorithms.
Don't be affraid: a lot of thought has gone into Subversion (and still
goes into it); we're working hard to store your data as efficiently as
possible and we're still searching for better ways to do it. Just
install it and upgrade every now and then and you'll benefit from our
research. No need to do you own (unless you -ofcourse- want to
contribute some back to the community).
bye,
Erik.
