Add histograms to record document.execCommand.
Add a UMA histogram metrics counting commands when document.execCommand is called.
Each histogram id corresponding to a command name is in EditorCommand.cpp:
https://src.chromium.org/viewvc/blink?revision=165849
The new UMA is WebCore.Document.execCommand and the corresponding implementation is done:
https://src.chromium.org/viewvc/blink?revision=172020&view=revision
This CL rewrites the summary of WebCore.Editing.Commands and let WebCore.Document.execCommand use the original summary because we found that WebCore.Editing.Commands doesn't represent what we want to do as the original summary says.
That's because the new UMA is needed.
