Not that I have seen.  I did forget to send the previous reply, should 
now be there.

Well my take is that most of the tests do not care about autocrlf, they 
are checking that the right file or error is happening.  For example:


   git commit -m "c1"
  echo foo >file2
  git checkout -- file2

just wants to know that file2 is correctly reverted to before the 
change.  The fact that file2 can have LF -> CRLF if autocrlf=true is not 
what is being checked for here.  There are several tests like 
t0020-crlf.sh that are checking that the right thing happens.

I am assuming that t7610-mergetool.sh add the test for autocrlf=true 
because of some issue (bug?) that was fixed.  However I have not done a 
full look into way the test is there.  I was focused on getting the 
tests to pass.

Also I do expect that most people will run the tests in the default mode 
only.  I have no plans on add the "run the tests in all possible 
settings of autocrlf".

This set seems like a subset (but still big) change on the path of 
getting git to work and pass the tests under CYGWIN on a text mount.  
That change is still in progress and not yet ready for the list.
