git itself handles history tracking across renames if the first commit
with the new name has the exact same sha1 hash.

This is what "git mv" does, ie.
        git mv git-cloud.el git-cloudly.el
        git commit -m "Rename git-cloud.el to git-cloudly.el"
gives something that "git log --follow -- gnus-cloudly.el" can use to
list the history across the rename.

Tool support is something else.  There used to be
  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=8756
which was merged with
  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=19045
and both closed as fixed, however 'C-x v l' doesn't do the right thing
in emacs 25.2.1, history stops at the rename.

Annotate, ie. 'C-x v g' will show changes from across the rename, and
pressing 'd' (to see the diff) and 'l' (to see the log message) on an
annotated line, will show the correct information
