Thank you for the patch. Sorry that I won’t be taking it, though.

The immediate reason is that your change makes the script pick up any after/syntax/css.vim – not specifically the one belonging to this plugin.

The broader reason is that in looking at how to address that, it seems to me that the script must long have gone entirely broken, regardless of the flavour of Vim in use. It was a long time ago that the plugin consisted only of after/syntax/css.vim. It was an even longer time ago that placing that path directly below ~/.vim was the usual method of installing the plugin. I’m pretty sure that either the time accrued to autoload/css_color.vim is more important, and/or the time accrued to other files also needs accounting for. The pattern match is not written to expect any part of the contemporary situation.

I don’t know off hand how the correct patch would have to look like so I can’t really give guidance on updating it.

I've been using this to hunt down my performance issues described in #126 - but this was quite a while ago.

Thanks for the explanation! Closing this.
