Finally, I've found where the bug is:

It is in DrawStatusTextW, here:

        if (*text == '\t') {
            text++;
            align = DT_CENTER;
            if (*text == '\t') {
                text++;
                align = DT_RIGHT;
            }
        }

http://source.winehq.org/source/dlls/comctl32/commctrl.c#L538

As you see, it only checks if the first character is \t or the first two of
them are. Test it with control spy and you'll see, that if you put tab or
double tab at the beginning of the string it will align text, but it won't if
the tab occurs further in string. However, there are no such restrictions in
specification (see above).

As a test cases these should work this way:

L\tC\tR > |L         C          R|
L\t\tR >  |L                    R|
\tC\tR >  |          C          R|

My knowledge of C is very limited, and currently I am not sure if I am able to
fix this (or rather that my fix would work well and won't spoil anything).
