Checking hg exit code in Windows batch

[Jan Vrany]

Hi,

I tried with 3.0.1 and same result.
Funny enough, I tried on another Win 7 machine (almost the same setup)
and there it works.

I don't really understand why is that. But apparently the problem is not
only in mercurial but rather some combination of OS, DLLs, hell knows what.

Sorry, I should have tried that before posting here.
