Unlike some of the other answers, I don't think it's at all clear what
to do here.
1) Change the tag to source=nearmap: that's misattributing any parts
of the way that you didn't update
2) Change the tag to source=yahoo;nearmap: tedious, but relatively accurate
3) Add source tags to the individual nodes that you moved: I often do
this, but it's probably causing database bloat
4) Add source tags just to the changeset: IMHO this is insufficient,
as it requires enormous effort later to retrieve changeset information
and match it against ways, or vice versa.
It's hard to say exactly at what point a way is no longer "sourced"
from yahoo. What if hypothetically, the surface information came from
yahoo, but the locations came from nearmap? It's tricky.
I would love to know whether Yahoo or Nearmap actually gives a damn.
