blame would segv if given -L <lineno> with <lineno> past the end of the file. While we're fixing the bug, add test cases for an invalid <start> when called as -L <start>,<end> or -L<start>.
Signed-off-by: Jay Soffian <jaysoffian@gmail.com> --- bottom is start and top is end, which seems backwards to me, but alas, it is what it is. :-)
