Unfortunately "git log --follow <filename>" works correctly only
on relative simple histories.  You are of course welcome to improve
this part of git.

Simple workaround is to use "git log <file>" (optionally using
--diff-filter) to get when file vanished, check using "git show" or
"git whatchanged" on boundary commit, then use 
"git log -C -C -- <old name> <new name>"
