.vim/syntax/sql.vim：处理“*.sql”的 BufRead 自动命令时检测到错误

问：

我尝试为 sql 保存这个 vim 语法文件，但是当我在 vim 中打开一个 sql 文件时，我得到了很多很多这样的东西：

Error detected while processing BufRead Autocommands for "*.sql"..function dist#ft#SQL[4]..FileType
Autocommands for "*"..Syntax Autocommands for "*"..function <SNR>4_SynSet[25]..script /home/bernie/.

等等等等

Here's the first part of the linked syntax file

" Vim syntax file for SQL
" Language:     SQL standard / Support for drivers specifics
" Maintainer:   Julien Rosset <[email protected]>
"
" URL:          https://github.com/vim-highlight/sql/
" Version:      0.0.1

" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
if version < 600
  syntax clear
elseif exists("b:current_syntax")
  finish
endif

" Initialize options {{{
let s:driver         = vim_highlight#core#options#getValue('driver'        , '')
let s:case_sensitive = vim_highlight#core#options#getValue('case_sensitive',  0)
" }}}

" Case matching {{{
if s:case_sensitive
    syntax case match
else
    syntax case ignore
endif
" }}}

call extend(g:vim_highlight#core#options#default#common, { 'skipempty': 1, 'skipnl': 1, 'skipwhite': 1, 'contained': 1 })
call extend(g:vim_highlight#core#options#default#region, { 'keepend': 1 })

let s:predicats = { 'root': 'sql' }

由于这是某人公开发布的语法文件，看到这么多错误让我觉得我的 vim 设置一定存在一些更广泛的问题。我使用的是 8.2.1847 版。

我需要什么才能使附加的 vim 语法文件正常工作？
