Subversion branch deltification policy is more space-hungry than CVS

Subversion stores more fulltexts than CVS, for the same history, if branching is used at all.

This becomes very visible when people convert from CVS to subversion, and their repositories increase significantly in size.

CVS stores 1 fulltext per file.

SVN stores 1 fulltext per file *plus* an additional fulltext for every branch on which a file is modified.

This is a tradeoff of space vs. checkout speed which is different to that made by CVS, and needs to be carefully considered, as it
may well dissuade people from switching from CVS to SVN.
