Re: [BUG?] blame: Odd -L 1,+0 behavior

I don't know what "zero-indexed" means, but +2 means "starting from the line I told you earlier, give me two lines". Likewise -2 means "ending at the line I told you earlier, give me two lines". As a side effect of the internal implementation of this logic -L 5,3 means the same thing as -L 3,5 but that is not an intended nor documented behaviour.

The parsing code is lax in the sense that rejecting nonsensical input like "-L 10,-100" and "-L 2,+0" as an error was not considered a primary goal. The only error checking it does is to make sure it does not parse numbers that it cannot use (i.e. start from line 30 in a file that does not have that many lines).
