Sounds good to me.  One question I have is whether to leave the assertion that 
we've been discussing.  When you introduced it in May 2018, the commit message said

     Cygwin: TEST only: Add a buffer underrun assertion to symlink_info::check
     [...]
     Revert before release.

On the other hand, the assertion has caught two bugs in the last few months, and 
who knows whether there are more.  So I'd probably be inclined to leave it for a 
while longer.

Ken
