[TYPO3-core] RFC #15020: Enhancement of t3lib_div::testInt

Hi,

Actually it states:

"In general there should be a single return statement in the function (see
the preceding example). 
However a function can return during parameter validation before it starts
its main logic"

Though this isn't parameter validation, I wouldn't read "in general" as
"only a single return is allowed" ;).

Cheers,
