regression in mq: directory names are uppercased since hg 2.0.2 and thg 2.2.2

[Dominik Psenner]

I investigated a little further into this problem and this is the result:

The symptoms were reproducible by doing a simple "hg add" / "hg forget"
cycle with thg. While doing the equivalent in console - thus calling
mercurial directly - worked just fine. So this seems to be a problem within
thg for at least versions > 2.1.4.

Version              | thg    | console
----------------------------------------
Thg 2.2.2 (hg 2.0.2) | broken | works
Thg 2.1.4 (hg 1.9.3) | works  | works

hg, nore mq do not seem to be innocent.

Cheers
