git-svn log: include commit log for the smallest revision in a range

The "svn log -rM:N" command shows commit logs inclusive in the range [M,N].
Previously "git-svn log" always excluded the commit log for the smallest
revision in a range, whether the range was ascending or descending.  With
this patch, the smallest revision in a range is always shown.

Updated tests for ascending and descending revision ranges.
