Completion for cd .. differs from bash

[EdVanDance]

Hello,
I searched for more than an hour through the issue tracker and surprisingly didn't find anything. Whenever I'm using bash or zsh I often hit cd ..TAB which adds /, further pressing TAB shows the contents of the parent directory for completion.

With clink when I type out cd ..\ (manually adding the \), everyhting works fine. But without the \ pressing TAB just adds a space instead of \.

Would be very nice if cd ..TAB would add \.

Regards,
Ed

Edit: My environment: clink 0.4.3, Windows 7 x64

Edit 2: Just tried with an other command, e.g. type ..TAB, nothing happens here. I would also expect an \ to be added.
