runtime(doc): Clarify list-concatenation a bit more
Make doc list-concatenation more clear as for += and extend().
1. describe `+=` for list-concatenation more accurately
2. add `extend()` example for list-concatenation
3. Fix CI errors for missing helptags reference |+=|

When the terminal emulator sends an OSC sequence to Nvim (as a response
to another OSC sequence that was first sent by Nvim), populate the OSC
sequence in the v:termresponse variable and fire the TermResponse event.
The escape sequence is also included in the "data" field of the
autocommand callback when the autocommand is defined in Lua.
This makes use of the already documented but unimplemented TermResponse
event. This event exists in Vim but is only fired when Vim receives a
primary device attributes response.
Fixes: https://github.com/neovim/neovim/issues/25856
Problem:
The swapfile "E325: ATTENTION" dialog is displayed when editing a file
already open in another (running) Nvim. Usually this behavior is
annoying and irrelevant:
- "Recover" and the other options ("Open readonly", "Quit", "Abort") are
almost never wanted.
- swapfiles are less relevant for "multi-Nvim" since 'autoread' is
enabled by default.
- Even less relevant if user enables 'autowrite'.
Solution:
Define a default SwapExists handler which does the following:
1. If the swapfile is owned by a running Nvim process, automatically
chooses "(E)dit anyway" (caveat: this creates a new, extra swapfile,
which is mostly harmless and ignored except by `:recover` or `nvim -r`.
2. Shows a 1-line "ignoring swapfile..." message.
3. Users can disable the default SwapExists handler via `autocmd! nvim_swapfile`.

Also:
- fix a missing `<` in builtin.txt.
- edit `:function` `{name}` wording to match the change made for the docs above
by Justin in #10619.
- link to `*vimrc*` rather than `*init.vim*` in repeat.txt change (as `init.lua`
may also be used).

Problem: The `'statuscolumn'` was not re-evaluated for wrapped lines,
when preceded by virtual/filler lines. There was also no way
to distinguish virtual and wrapped lines in the status column.
Solution: Make sure to rebuild the statuscolumn, and replace variable
`v:wrap` with `v:virtnum`. `v:virtnum` is negative when drawing
virtual lines, zero when drawing the actual buffer line, and
positive when drawing the wrapped part of a buffer line.
Problem: Unable to customize the column next to a window ('gutter').
Solution: Add 'statuscolumn' option that follows the 'statusline' syntax,
allowing to customize the status column. Also supporting the %@
click execute function label. Adds new items @C and @s which
will print the fold and sign columns. Line numbers and signs
can be clicked, highlighted, aligned, transformed, margined etc.
Problem: Help tag generation picks up words in code examples.
Solution: Skip over examples. (Carlo Teubner, closesvim/vim#10813)

- `col()`'s example was changed to use `:echowin` so that the message can be
seen with `showmode`. Use "\n" to force a hit-enter instead as `:echowin`
isn't ported.
- Replace interpolated string usage in syntax/modula3.vim (not ported).
- Add a space after the `wincmd =` examples in `*CTRL-W_=*` so that the inlined
code is highlighted properly when followed by a full stop.
