Avoided a potential misunderstanding that `throw e` would slice *any* `e` to `std::exception`.
The note about rethrowing appears to be written when the example of this item still did `catch (const exception& e)`, which was prior to commit d568d190f6, "Generalized E.15, closes#1848".
Fixes#1946:
- copy_trait type argument needs to be a container element type.
Use Value_type<Iter> like in other examples.
- Fix name typo in the definition of copy_helper.

* C 32 comments (#3)
* F.16 ("in" parameters): Move Matrix example to F.20 (return values) (#1922)
The `Matrix` example and the notes about assignment appear off-topic in rule F.16, as F.16 is specifically about "in" parameters.
With help from Sergey Zubkov.
* SL.io.50 (Avoid `endl`): Mention string streams (#1920)
Explicitly mentioned string streams as `endl` insertions into string streams do actually occur in the wild.
With help from Sergey Zubkov.
* Extended E.16 to include copy ctor for exception type, closes#1921
* Fix GitHub Actions build warnings, Marker style should be `*` (#1925)

When I stumbled upon E.19 "Use a `final_action` object to express
cleanup if no suitable resource handle is available" I was hopeful
that this `final_action`/`finally()` thing is from the STL, but, alas,
it isn't.
Make it clear that `finally` is a GSL construct.
The `Matrix` example and the notes about assignment appear off-topic in rule F.16, as F.16 is specifically about "in" parameters.

* conditionally unused parameters can be declared using maybe_unused attribute.
* move to Notes and add example
* whitespace?
* ok got the whitespace
* adjust example
