Re: [PATCH] blame: add --fuzzy-lines command line option

Isabella Stephens [off-list ref] writes:

If the -L option is used to specify a line range in git blame, and the
end of the range is past the end of the file, git will fail with a fatal
error. It may instead be desirable to perform a git blame for the line
numbers in the intersection of the file and the specified line range.

Even though erroring out upon such input was done as a deliberate
design decision, in retrospect, I do not think the design decision
made much sense.

The code already takes a nonsense input and tries to make best sense
of it, e.g. "-L10,6" is interpreted as "-L6,10" instead of erroring
out.  So if we were to do this kind of change, I suspect that it may
be better to do so unconditionally without introducing a new option.

Thanks.
