Merge lp:~bialix/bzr/hidden_attr_on_unicode into lp:~bzr/bzr/trunk-old

[Alexander Belchenko]

[Alexander Belchenko (bialix)]

Bzr has one latent bug related to create new .bzr directory inside unicode directory. The problem occurs when unicode path cannot be encoded in current user encoding, as pointed by INADA Naoki, see
https://bugs.launchpad.net/tortoisebzr/+bug/335362/comments/41

This is rare condition, but bug itself is very serious.
Please, merge for 1.17.

(This is 3rd version of my patch, started from merge directive in ML, and now I send it to LP as jml and vila suggested).

As mentioned on Bundle Buggy, you need to add
"requireFeature(Unicode...)" for the tests, otherwise:

As I said in ML it's all about windows behavior. Can I just skip tests
when running not on Windows? They have no sense for Linux.

Sorted out on IRC, I'll merge.
