This is odd.  I suspect rewriting the paths like this is something in
the upstream Git project, rather than anything Cygwin-specific (although
clearly the issues it's causing are Cygwin-specific).  I don't think
there's enough information here for me to investigate or report
upstream, unfortunately; what I really need is information about what
triggers the behaviour so I can reproduce the problem.

If you manage to work out how to reproduce this behaviour, rather than
just noticing it after the fact, that would be incredibly useful and I
can take things from there.
