This sounds like a mintty issue, not a Cygwin DLL issue.  The Cygwin DLL
only provides the pseudo tty communication channel.  The interpretation
of the escape sequences is done in the terminal emulator.

Unfortunately I have not read anything from the mintty maintainer, Andy
Koppe, since mid-2013, neither here nor on the mintty mailing list.
There was also no upstream mintty release since April 2013.  I have
tried to contact Andy a couple of days ago but didn't get a reply yet.
I hope he's well.
