Empty input streams from wxHTTP never EOF

[nielsm]

wxHTTP http;
http.Connect(servername);
wxInputStream *stream = http.GetInputStream(path);

If the resource at path on the server is zero bytes, then stream->Eof() will never return true.

Tested on 2.8.10.

Forgot to mention, this bug may trace several years back. Ticket #3334 seems to be the same issue, though it was closed. The message says a fix was due for merging but perhaps that merging never happened...?

[vadz]

It looks indeed the same as #3334 and the changes in it were never applied. Could you please test if changing this > to >= does indeed fix the problem?

[vadz]

The fix does seem to be correct to me so I'll apply it even without feedback about testing, at the very least it shouldn't break anything.

(In [63238]) Fix wxHTTPStream::Eof() to return true for empty HTTP resources.

Eof() never returned true when attempting to read an empty resource before.

Closes #11596.
