This commit contains following changes:
  - Add "execute" verb in first bullet, sentence is missing a verb.
  - Swap second and third bullets.
  - Improve wording of third bullet by adding a statement about "try
    clause statement skipped, if exception occurred".

Replacing "before finishing `try` statements" with "just before
finishing exception handling", adds some more clarification about when
`finally` block gets executed.

End sentence with a colon punctuation, if next sentences contains
explanation of it.
