Push more member functions from EditCommand to CompositeEditCommand

[Ryosuke Niwa]

Right now EditCommand has many member functions that are overridden by CompositeEditCommand. However, some of them only make sense on CompositeEditCommand. We should move them to CompositeEditCommand since CompositeEditCommand now exists only at the time of initial application of the command.

Also, it doesn't make much sense for EditCommandComposition to share the same super class (EditCommand) with SimpleEditCommand and CompositeEditCommand.

Typo CreateLinkCommand.

> +    const VisibleSelection& startingSelection, const VisibleSelection endingSelection, bool wasCreateLink)

I suggest using was CreateLinkCommand as parameter name.

> Source/WebCore/editing/CompositeEditCommand.h:42
> +    static PassRefPtr<EditCommandComposition> create(Document*, const VisibleSelection&, const VisibleSelection, bool wasCreateLink);

Ditto.

> Source/WebCore/editing/CompositeEditCommand.h:48
> +    bool wasCreateLinkCommand() { return m_wasCreateLink; }

Again I would prefer m_wasCreateLinkCommand. It just feels more understandable.

> Source/WebCore/editing/CompositeEditCommand.h:55
> +    EditCommandComposition(Document* document, const VisibleSelection& startingSelection, const VisibleSelection& endingSelection, bool wasCreateLink)

Ditto.

> Source/WebCore/editing/CompositeEditCommand.h:62
> +    bool m_wasCreateLink;

Ditto.

> Source/WebKit2/WebProcess/WebPage/WebPage.cpp:2246
> +    frame->editor()->replaceSelectionWithText(text, selectReplacement, smartReplace);

I'm not sure this code is equivalent. The PreventNesting option seems to be lost.

> Source/WebKit/chromium/src/WebFrameImpl.cpp:1129
> +    frame()->editor()->replaceSelectionWithText(text, selectReplace, smartReplace);

Ditto.

> Source/WebKit/gtk/webkit/webkitwebframe.cpp:1001
> +    coreFrame->editor()->replaceSelectionWithText(text, selectReplacement, smartReplace);

Ditto.

> Source/WebKit/mac/WebView/WebFrame.mm:1049
> +    _private->coreFrame->editor()->replaceSelectionWithFragment(core(fragment), selectReplacement, smartReplace, matchStyle);

Ditto.

The patch shows build errors on mac.
It would be better to add layout tests for the fix relative to the spellchecker regression. If you want to write the test I could run it and validate it for you, if you want.

Will fix.

Sure, will change.

PreventNesting is always set in Editor::replaceSelectionWithFragment.

Let me split this patch into 3 pieces:
1a - Remove dependency on ApplyCommand in WebKit
1b - Fix a regression in SpellingCorrectionController
2 - Push member functions from EditCommand to CompositeEditCommand.

Sounds like a good plan to me.

The changes look good, but there is a build failure. Please fix that.

> +    EditCommandComposition* composition = cmd->composition();

Nit. I would ASSERT composition directly.
