Hi,

is there a way to tell git diff about lines that are uninteresting?
I mean lines which do not contain a lot of information and
appear several times in pre and post image.

For example whitespace or language dependent stuff like.
{
}
END_IF;
END_FOR;
end sub

I have seen diffs that containing 2 interesting hunks splitted by such 
boring lines.
(I have attached a anonymized version of a real world example where this 
happens)

I think the diff would be clearer when this boring line was added to the 
surrounding hunks.
I already tried patience diff but in my test case it changed nothing.
I am using git 1.7.10.

Thanks,
Greetings Peter

Hi,

does anybody have a idea if this is possible?
Or some comments if they would find such a feature useful?

Greetings Peter
