If you want to also guarantee that you can change to a relative
directory whose name begins with a -, you need:
cd -- "$( ... )"

Again, if you have the possibility of a relative directory name that
might begin with dash,
cd -- "$(/bin/dirname -- "$(...)")"

Ah - you are using cygpath, which can guarantee an absolute name (and
therefore avoid an argument beginning with dash).
