Fix confusing text in E.61

[AndrewPardoe]

This example is used in ES.60--no naked new --and ES.61-- delete[] / delete .

The text in E.61 is a bit confusing. I propose changing the text to read

"Note: This example not only violates the no naked new rule, it has many other problems."

or

"Note: This example not only violates the no naked new rule as in the previous example, it has many other problems."

We should of course preserve the link if we preserve the text about naked new
