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.
