I've been supporting use of git on cygwin since about 2008, this issue 
has never risen that I know. Whatever issue is being patched around 
here, if truly repeatable, should be handled by the cygwin dll as that 
code is focused on providing full linux compatibility. If git on linux 
does need this patch, git on cygwin should not, either. So, I vote 
against this.
