Thanks, Kirill. :)

I must confess in reality I didn't encounter white-space changes a lot, but
mostly on moving the code around either e.g. by putting things into, or out of,
"if/for" blocks, or moving code between files.

I used git-blame a lot not to looking for people to blame but to dig history of
code changes, not sure about how others do that.  So maybe it's just that I
didn't do it right beforfe, and I'll be more than glad to learn if there's more
tricks like the "-w" one (which I don't know before..).
