[x265] note: history rewrite

[Steve Borho]

Hello,

I pushed a patch today with the wrong author attribution. I've fixed the
revision and re-pushed. If you pulled during the window that this
revision existed your tree will have changeset a13952e1c9ec and two
default heads.

If your repo has a13952e1c9ec you can either reclone or strip the
offending changeset and ancestors via:

 hg strip a13952e1c9ec

if you don't have a strip command enabled, use

 hg --config extensions.strip= strip a13952e1c9ec
