[PATCH v5 0/2] blame and log: prevent error if range ends past end of file

[istephens]

Okay, I think that sounds reasonable. I've amended the patch so that the
line number is clipped to 1 when reading in a line range. And -L,-n is now
treated the same as -L1,-n i.e. it will blame (or log) the first line of the
file only.
