Use thing-at-point for proper word recognition

So it can be used in code buffer as well. (current-word) only returns a
symbol, so look up fails most of the times.

On my emacs 24.3.1 thing-at-point has a single parameter so your code fails. BTW: the function word-at-point meaning (thing-at-point 'word) might be a good replacement here.

I also notified that in a lot of case (current-word) is more suitable thant (word-at-point).

For example, compound words (with hyphens) are returned by current-word but not by word-at-point. current-word also tries harder to find a valid word, word-at-point will more likely return nil.

I prefer the behaviour of current-word.

Maybe we can add prefix argument to it. The default behavior is for only one word and with prefix argument, use (current-word). Otherwise we cannot look up for word, i.e. I want to look up for the word thing in thing-at-point, but current word returns the whole thing-at-point word and result in word not found. Maybe we can change at least dictionary-lookup-definition command? It should look for a single word by default.
