Non-string keys?

[sun]

I don't know whether this is an actual problem, only stumbled over the question while reviewing the code:

merge/src/merge.js

Line 31 in dd46140

primary = cloner.deep.merge(secondary, primary);

Shouldn't this be merging the requested key only?

 primary[keyName] = cloner.deep.merge(secondary[keyName], primary[keyName]);

… so that only the specified key is merged, regardless of what type it is?

Feel free to close if invalid.
