[CLN-list] doc: "Obfuscating operators"

Regarding the entry "Obfuscating operators" in the doc: I strongly suggest to remove the section and enable the shortcut operators by default. People who do not want to use them don't have to. Giving a opinion as a fact is not very helpful. For me the shortcut operators as in a+=b are more readable than the long a=a+b form. You may want to keep the remark the in CLN there is no performance gain in using the shortcut forms so people who dislike them know they can stick to the long form without a performance penalty. cheers, jj
