It seems you're right, it isn't a regression, but it's still a bug.

cd /usr/..../var (with four dots) works the same way.

You can easily nest those:

$ pwd
/bin/.../bin/.../bin/.../bin/.../bin/.../bin/.../usr/.../usr/.../usr/.../usr/...
/var/.../usr/local/bin/.../src/.../src/.../src/.../src/.../src/.../src/.../src/.
../src/.../src/.../src/.../src/.../src/.../src/.../src/.../src/.../src/.../src/.
../src

$ cd .../src
bash: cd: .../src: File name too long

$ ls
ls: .: No such file or directory

Funny that if I start a windows shell now, it will have the right working 
directory (/usr/local/src in this case).
