When adding `workspace/didChangeWorkspaceFolders` support to my [language server](https://github.com/elixir-tools/next-ls), I noticed that when neovim removes a workspace, it sends an empty table (which is serialized to an empty JSON array) for the value in the `added` field.
This does not follow the spec; the `added` table should just be empty.
The following error led me to this discovery. Note the payload includes `"added" => [[]]`:
```
22:46:48.476 [error] LSP Exited.

In the case you hit this warning in a buffer (like with C++ and clangd),
this message potentially fires over and over again making it difficult
to use the editor at all.
Problem:
netrw may conflict with the Nvim default "gx" mapping.
Solution:
Initialize keymapping earlier by moving it to vim._init_default_mappings().
That also avoids needing to check maparg().
* docs(lua): teach lua2dox how to table

No more need to mark local functions with @private
* docs(lua): mention @nodoc and @meta in dev-lua-doc

Problem:
Bash language server returns "hover" markdown content that starts with
a code fence and info string of `man` preceded by whitespace, which Nvim
does not render properly.
See 0ee73c53ce/server/src/server.ts (L821C15-L821C15)
```typescript
function getMarkdownContent(documentation: string, language?: string): LSP.MarkupContent {
return {
value: language
? // eslint-disable-next-line prefer-template
['``` ' + language, documentation, '```'].join('\n')
: documentation,
kind: LSP.MarkupKind.Markdown,
}
}
```
For example,
```
``` man
NAME
git - the stupid content tracker
```
```
If I remove the white space, then it is properly formatted.
```
```man instead of ``` man
```
Per CommonMark Spec https://spec.commonmark.org/0.30/#info-string
whitespace is allowed before and after the `info string` which
identifies the language in a codeblock.
> The line with the opening code fence may optionally contain some text
> following the code fence; this is trimmed of leading and trailing
> spaces or tabs and called the [info
> string](https://spec.commonmark.org/0.30/#info-string). If the [info
> string](https://spec.commonmark.org/0.30/#info-string) comes after
> a backtick fence, it may not contain any backtick characters. (The
> reason for this restriction is that otherwise some inline code would
> be incorrectly interpreted as the beginning of a fenced code block.)
Solution:
Adjust stylize_markdown() to allow whitespace before codeblock info.
Problem:
The default "#" mapping fails on the following example after v$h# with
cursor at start of the first line:
aa?/\bb
aa
aa?/\bb
Solution:
Also escape "?".
Problem: `hl_mode` for inlay hints is `combine`, causing bugs like
inlay hints using highlights from the previous character
(#24152, #24068)
Solution: Don't use hl_mode=combine for inlay hints.

Problem: When using treesitter foldexpr,
* :diffput/get open diff folds, and
* folds are not updated in other windows that contain the updated
buffer.
Solution: Update folds in all windows that contain the updated buffer
and use expr foldmethod.
Problem:
The parent commit added a new vim.get_visual_selection() function to
improve visual star. But that is redundant with vim.region(). Any
current limitations of vim.region() should be fixed instead of adding
a new function.
Solution:
Delete vim.get_visual_selection().
Use vim.region() to get the visual selection.
TODO: fails with visual "block" selections.
Problem:
Visual mode "*", "#" mappings don't work on text with "/", "\", "?", and
newlines.
Solution:
Get the visual selection and escape it as a search pattern.
Add functions vim.get_visual_selection and _search_for_visual_selection.
Fix#21676
Problem:
Showing an error via vim.notify() makes it awkward for callers such as
lsp/handlers.lua to avoid showing redundant errors.
Solution:
Return the message instead of showing it. Let the caller decide whether
and when to show the message.

Rejected experiment: move vim.ui.open() to vim.env.open()
Problem:
`vim.ui` is where user-interface "providers" live, which can be
overridden. It would also be useful to have a "providers" namespace for
platform-specific features such as "open", clipboard, python, and the other
providers listed in `:help providers`. We could overload `vim.ui` to
serve that purpose as the single "providers" namespace, but
`vim.ui.nodejs()` for example seems awkward.
Solution:
`vim.env` currently has too narrow of a purpose. Overload it to also be
a namespace for `vim.env.open`.

Problem: in #24046 the signature of buf.clear_references() changed, which
indirectly breaks callers that were passing "ignored" args.
Solution: because util.buf_clear_references() already defaulted to "current buffer",
the change to buf.clear_references() isn't actually needed, so just revert it.
perf(treesitter): cache vim.treesitter.query.get
Problem:
vim.treesitter.query.get searches and reads query files every time it's
called, if user hasn't overridden the query. So this can incur slowdown
when called frequently.
This can happen when using treesitter foldexpr. For example, when using
`:h :range!` in markdown file to format fenced codeblock, on_changedtree
in _fold.lua is triggered many times despite that the tree doesn't have
syntactic changes (might be a bug in LanguageTree). (Incidentally, the
resulting fold is incorrect due to a bug in `:h range!`.) on_changedtree
calls vim.treesitter.query.get for each tree changes. In addition, it
may request folds queries for injected languages without fold queries,
such as markdown_inline.
Solution:
* Cache the result of vim.treesitter.query.get.
* If query file was not found, fail quickly at later calls.

Commit 37079fc moved inlay_hint to vim.lsp() but in the process did
missed converting a call to disable/enable which are now local.
Fixes the below error when trying to toggle inlay hints.

Problem: Treesitter fold is not updated if treesitter hightlight is not
active. More precisely, updating folds requires `LanguageTree:parse()`.
Solution: Call `parse()` before computing folds and compute folds when
lines are added/removed.
This doesn't guarantee correctness of the folds, because some changes
that don't add/remove line won't update the folds even if they should
(e.g. adding pair of braces). But it is good enough for most cases,
while not introducing big overhead.
Also, if highlighting is active, it is likely that
`TSHighlighter._on_buf` already ran `parse()` (or vice versa).
Problem: Not all cabal config files are recognized.
Solution: Add a couple of patterns. (Marcin Szamotulski, closesvim/vim#12463)
166cd7b801
Also:
- Do not expand Lua patterns in environment variables used in file patterns.
- Test $XDG_CONFIG_HOME on Windows, as it can be used by Nvim (and the runner
sets it).
