Improve order of paragraphs on line splitting (#3270)

Browse Source 
These two paragraphs were tucked away at the end of the section, after
the diversion on backslashes. I nearly missed the first paragraph and
opened a nonsense issue, and I think the second belongs higher up with
it too.

If a data structure literal (tuple, list, set, dict) or a line of "from" imports cannot
fit in the allotted length, it's always split into one element per line. This minimizes
diffs as well as enables readers of code to find which commit introduced a particular
entry. This also makes _Black_ compatible with
[isort](../guides/using_black_with_other_tools.md#isort) with the ready-made `black`
profile or manual configuration.
You might have noticed that closing brackets are always dedented and that a trailing
comma is always added. Such formatting produces smaller diffs; when you add or remove an
element, it's always just one line. Also, having the closing bracket dedented provides a
clear delimiter between two distinct sections of the code that otherwise share the same
indentation level (like the arguments list and the docstring in the example above).

_Black_ prefers parentheses over backslashes, and will remove backslashes if found.
@ -127,19 +140,6 @@ If you're reaching for backslashes, that's a clear signal that you can do better
slightly refactor your code. I hope some of the examples above show you that there are
many ways in which you can do it.

### Line length
You probably noticed the peculiar default line length. _Black_ defaults to 88 characters
