Plain Vim spat a wall of `W18: Invalid character in group name` on
every buffer load because `syntax/vimwiki.vim` declared the
LSP-token highlight defaults with Tree-sitter-style names
(`@vimwikiHeading.level1`, `@vimwikiBold`, …). Those work on Neovim
but Vim rejects `@` and `.` in group names.
- `syntax/vimwiki.vim` now guards the `@vimwiki*` block with
`has('nvim')`. The static regex fallback below it (which uses
Vim-compatible `nuwiki*` group names) keeps highlighting working
on plain Vim.
While reproducing, also noticed `autoload/nuwiki/lsp.vim`'s
`s:bin_path` reported the binary at `/home/gfranco/bin/nuwiki-ls`
(only two dirs under `$HOME`) instead of
`/home/gfranco/git-repositories/nuwiki/bin/nuwiki-ls`. Cause:
`expand('<sfile>:p')` inside a function resolves to the *calling*
script at invocation time, not this autoload file. Captured the
plugin root via `<sfile>` at script-load time into a new
`s:plugin_root` and used it in `bin_path()`.
Verified with `vim -u .vimrc index.wiki`:
- `:messages` is empty of W18 warnings.
- The "binary not found" path (when no built binary exists) now
prints the correct repo-relative path.
Total 377 Rust tests still pass.
