If the -L option is used to specify a line range in git log, and the end of the range is past the end of the file, git will fail with a fatal error. This commit prevents such behaviour - instead we perform the log for existing lines within the specified range. This commit also fixes a corner case where -L ,-n:file would be treated as a log over the whole file. Now we treat this as -L 1,-n:file and blame the first line of the file instead.
