[Lazarus] Error in UTF8CompareText comment

[Jürgen Hestermann]

There is a comment for UTF8CompareText in LazUTF8 which is contradictorily:

// Returns: < 0 if S1 < S2, 0 if S1 = S2, > 0 if S2 > S1.

But S1 < S2 is the same as S2 > S1.
In the first case the result should be < 0 and in the second one > 0.

It cannot even be retrieved from the code how it realy works (unless you are fit in assembler).
So when will the result be positive and when negative?
