Old regexpengine causes redrawtime exceeded

[adrigzr]

When having the following settings on vimrc:

syntax on
set regexpengine=1

And opening the following file:

function lala(files, options) {
  const outputDir = path.join(this.options.cwd, options.output);
}

With the command:

$ vim -N -u vimrc file.ts    

Vim is very slow opening the file and after some time throws: 'redrawtime' exceeded, syntax highlighting disabled

The readme mentions explicitely to set the regex engine via set re=0

Note: set re=0 explicitly in your vimrc. Old regexp engine will incur performance issues for yats and old engine is usually turned on by other plugins.

BTW, when talking about old regex engine, I'm not sure how old it is. If this article is related, it would be pre-dating 2010... and that would be pretty old indeed.
