ES section, different stuff (#1473)

* ES section, different stuff

- ES.26: same capitalization for all function names in example
- ES.34: fix wrong formatting (first line of example was formatted as text)
- ES.46: corrected value in comment (new value read out in debugger)
- ES.46: Capitalize Enforcement bullet points (as in other ES rules)
- ES.65: fix formatting of code after list (compare https://meta.stackexchange.com/a/34325/172717)

* review-feedback from jwakely

and:
- ES.46/ES.47: added period at end of sentence

 A good analyzer can detect all narrowing conversions. However, flagging all narrowing conversions will lead to a lot of false positives. Suggestions:
 
-* flag all floating-point to integer conversions (maybe only `float`->`char` and `double`->`int`. Here be dragons! we need data)
+* Flag all floating-point to integer conversions (maybe only `float`->`char` and `double`->`int`. Here be dragons! we need data).
