Catch compound verbs

[RichardLitt]

I ran into an issue in the React docs that caused me to misparse a sentence: a compound verb.

...it only shallow copies log n objects...

There ought to be a way to catch ADJ+V combinations like this. A suggested change which I think is easier to read would be:

...it only makes a shallow copy of log n objects...

How about:

..it only shallowly copies log n objects...

Is this acceptable? It is a ADV+V combination which is normally considered ok, but It seems to have a similar problem.

Or:

...it only shallow-copies log n objects...

Both of those would be fine. I think the former is better, as it is more extensible.
