git-svn log: handle unreachable revisions like "svn log"
When unreachable revisions are given to "svn log", it displays all commit logs in the given range that exist in the current tree. (If no commit logs are found in the current tree, it simply prints a single commit log separator.) This patch makes "git-svn log" behave the same way. Ten tests added to t/t9116-git-svn-log.sh.
