The above two points are related: the current master causes git to abort 
before writing the index:

 >git checkout -f origin/master
error: git-checkout-index: unable to create file t/t5100/nul (File exists)
 >git mv t/t5100/nul t/t5100/nul-file
fatal: not under version control, source=t/t5100/nul, 
destination=t/t5100/nul-file

So, there is now a range of git's history that is unusable (and 
non-bisectable) on Windows, at least from the porcelain. And apparently, 
somewhere in that unusable history, a change was introduced that causes 
test failure on Cygwin. Great...
