This wording was valid for an old version of that patch that foolishly
add a switch to "map" to allow recording history. Happily we found
a better solution. Now commands inside user mappings never add to
prompt history (unless you use "set-register"), so be clear about that.
So far they have only been talked about in source code
(HistoryRegister), not in documentation.
Let's give them an official name so users can find them better;
"prompt history register" seems better than "history register" since
the former gives more context. OTOH, in future other registers (like @)
could grow into history registers, so I'm not sure.
State that the history registers are only changed by _interactive_
prompts; that's not quite true yet for user modes but I'll push a
separate fix for that.
We often use the pattern «map global normal ": foo"». The space
after the colon is unnecessary since execution of the mapping won't
add to history anyway, since 217dd6a1d (Disable history when executing
maps, 2015-11-10).
With the parent commit, the space is no longer necessary for user
mappings, so there is no reason to continue the cargo-cult.
Remove the space from mappings to set a good example.
Commit 217dd6a1d (Disable history when executing maps, 2015-11-10)
made it so with
map global normal X %{:echo 123<ret>}
X does not add to prompt history (%reg{:}).
Unfortunately this behavior was not extended to mappings in the "user"
keymap, nor to mappings in custom user modes.
In my experience, not adding to history is almost always the expected
behavior for mappings. Most users achieve this by adding a leading space:
map global user X %{: echo 123<ret>}
but that's awkward. We should have good defaults (no nnoremap)
and map should work the same way across all modes.
Fix this by also disabling history when executing user mappings. This
is a breaking change but I think it only breaks hypothetical scenarios.
I found some uses where user mappings add to history but none of them
looks intentional.

`x` is often criticized as hard to predict due to its slightly complex
behaviour of selecting next line if the current one is fully selected.
Change `x` to use the previous `<a-x>` behaviour, and change `<a-x>` to
trim to fully selected lines as `<a-X>` did.
Adapt existing indentation script to the new behaviour
Cross-reference the "completers" option, and explain how filtering works.

Even though the synopsis mentioned `kak -f` accepts filenames, it wasn't clear
to me that Kakoune would filter them in-place by default (I guess I assumed it
would write them to stdout like sed(1)).
For the "completions" option type, the documentation states that |
and \ need to be escaped as \| and \\.
The same parser is for other option types that are lists-of-tuples:
range-specs and line-specs, so they need escaping too. Document that.
Only their last element can contain arbitrary data, so range-specs
and line-specs could work without escaping if we tweaked the parser.
The prologue led some users to believe the implementation was compliant with ECMAScript let alone some differences (who *are* documented at the end of the page).
