Aha... well even if this is so, the effects of this will at least be mitigated
by the fact that libcurl will still canonicalize them even if it wouldn't be
perfect.

I mean a user who wants to compare two URLs should make sure to canonicalize
*both* of them before the comparison. Then such suble details such as the one
mentioned above will actually not matter since the end results from both those
URLs should be the same. Even if another library with more specific domain
knowledge possibly would end up with a slightly different output.

Or am I wrong?
