-a non-zero number of bytes have been read.
+In wxWidgets 2.6.x and below some streams returned Eof() when the last
+byte had been read rather than when an attempt had been made to read
+past the last byte. If you want to avoid depending on one behaviour or
+the other then call \helpref{LastRead()}{wxinputstreamlastread} to
+check the number of bytes actually read.
