Fixing the last shell32/shlfileop tests on Windows (< Win7)

[Paul Vriens]

Hi,

In my attempt to have no failures on WinMe I changed some W-functions 
into their A equivalent.

The problem with some Russian (only?) versions of XP is that in 
test_sh_path_prepare() we create a directory with the name "c:\Ä". This 
name is thrown through WideCharToMultiByte(CP_ACP ....) and we check 
with A-calls for the existence of this directory. This is the point 
where it fails. Doing these checks with W-calls is fine.

Is this some quirk of WideCharToMultiByte or does Russian in combination 
with using an A-function (GetFileAttributesA) present the issue?

The easy way out here is to just skip the tests on WinMe and stick with 
the W-functions. Having two codepaths is also possible (not pretty) and 
would only present an issue (I assume) if we ever have a Russian WinMe 
in our tests ;).

Paul.
