Interesting bug with Tk 8.5 and 8.6 on Windows

[Wojciech Kocjan]

Hi,

I just found something I think is a Tk bug that happens on Windows 7
(I guess all Windows), with ActiveTcl8.5.9.1.294121 and quite recent
Tk 8.6 build I had on my HDD:

1/ tk_getOpenFile -initialdir C:/WINDOWS -multiple 1
2/ select any file on a different drive - in my case D:/testfile
3/ outputs in C:/WINDOWS/D:/testfile

Not providing -initialdir and choosing from a different drive than the
original one also causes this. It also only happens with -multiple 1.

It is easy to work around in my code, I want to file a bug on SF but
just wanted to see if anyone knows if this is a known bug/issue? SF
tracker was down for me at the moment (HTTP 500 (Internal Server
Error)).
