Summary: ReadString() in htmlfilt.cpp requires streams of known size

Initial Comment:
file src/html/htmlflt.cpp: Function ReadString

static void ReadString(wxString& str, wxInputStream* s, wxMBConv& conv);

Uses wxInputStream::GetSize() to determine the size of a stream. Compares size to ~0 to find out whether the stream knows its size. Problem: Method wxInputStream::GetSize() is specified to return 0 on unknown stream size. So, the fallback strategy of ReadString will never run. Wither use wxInputStream::GetLength() here or test for size 0 (that may also result from an empty stream).
