Fallback manual download saving in TW280 displays two messages

When trying the direct online save in IE (ver 9, very old I guess), it does not open a (browser) save dialogue box but instead TW gives a message: RIGHT CLICK HERE to download/save main TiddlyWiki file Downloading/saving main TiddlyWiki file ...and what I'm questioning is that both of these lines are links. If this is intentional, it is a bit unclear for the user what to do. Or maybe it's just my old IE (v9)

manualDownloadSaveFile() displays a message, "RIGHT CLICK HERE....", which is correct. However, the higher-level saveMain() then displays the second message, which is only supposed to be shown if automatic HTML5DownloadSaveFile() was triggered. The fix is to suppress the second message when the fallback manual download saving is used.
