Re: [PATCH] log: prevent error if line range ends past end of file

> 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.

> 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.
