* WebCoreSupport.subproj/WebSubresourceClient.m:
        (+[WebSubresourceClient startLoadingResource:withURL:referrer:forDataSource:]):
	Check for errors by looking at the return value from loadWithRequest: rather than
	making a separate call to canInitWithRequest.

        * WebView.subproj/WebBaseResourceHandleDelegate.h: Add boolean success/failure result
	loadWithRequest:.
        * WebView.subproj/WebBaseResourceHandleDelegate.m:
        (-[WebBaseResourceHandleDelegate loadWithRequest:]): Return NO if we fail to make a handle.

        * WebView.subproj/WebDataSourcePrivate.m: (-[WebDataSource _startLoading]):
	Check result of loadWithRequest: and complain if it's NO.

        * WebView.subproj/WebMainResourceClient.m: Tweak whitespace.
