Use:

  git log --format=%H -M --name-status --follow -- path

I just tried it:

$ git log --format=%H -M --name-status --follow gerrit-prettify/src/main/resources/com/google/gerrit/prettify/client/prettify.js 8db22c85c49814b99639b2e6346583e9be4c289f

A       src/main/java/com/google/gerrit/public/prettify20090521/prettify.js

Yay, its been renamed 3 times in its life here.  :-)
