Overly large values also lead to excessive memory usage. I may have
only had 256M in my dev machine at the time I added this parameter:

git-svn: allow --log-window-size to be specified, default to 100
The newer default value should should lower memory usage for
large fetches and also help with fetching from less reliable
servers. Previously the value was 1000 and memory usage
got a bit high on some repositories and fetching became
less reliable in some cases.
