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
