pull: add hgsubversion.filestoresize to control memory consumption The configuration entry defines the size of the replay or stupid edited file store, that is the maximum amount of edited files data in megabytes which can be kept in memory before falling back to storing it in a temporary directory. Default to 200 (megabytes), use -1 to disable.
