preliminary patch

Missing a changelog and support for services that consume rich text data (e.g. New Email with Selection). Not sure how to best implement that yet.

r=me assuming that you tested how this affects Flash.

This function name doesn't look grammatically correct to me. Perhaps "get string for selection" or "get selection string" would be better?

> Source/WebKit2/WebProcess/WebCoreSupport/WebEditorClient.cpp:190
> -    EditorState state = m_page->editorState();

Should the rest of the function go to Page now? I think that it's best to not have much logic in WebEditorClient.cpp.

Using a special value for in-band error reporting doesn't seem to cause any issues here, but it would be nicer to not overload String semantics. If doing it differently is much harder, perhaps null could be the special value, not empty?

What is the danger in returning the empty string? Please add a comment to the code, because it looks surprising.

I thought the same thing, but this is the name that Pasteboard and WebPage already use...

Don't see why not.

Probably a good plan.

No danger, I was just trying to keep the behavior precisely the same in the case where the plugin doesn't support getStringSelection() (i.e. all non-PDFPlugin plugins).

To clarify, you just meant the call to updateGlobalSelection (and the implementation of updateGlobalSelection), right? Not the InjectedBundleEditorClient notification.

Still some things to discuss with Alexey, but I renamed getStringSelection -> getSelectionString (seems more important to have a good name here than match the rest of the code) and switched to using a null string for the "there is no selection" case.

Honestly, I did not look at what else the function did, so this was truly a question.
