Extra spaces in my tag list

[sally_maria]

Last year, I posted about getting a comma-separated list for my tags, and somebody helped me to sort it out.

Somehow, though, changes in the site or my layout mean that it no longer works quite right, and I was hoping somebody might help me to fix it.

The problem is with the commas after each item - there is always a space first, so the commas look rather odd.

At the moment I'm using

.module-tags_cloud .module-list-item { font-size: 12pt !important; }
.module-tags_cloud .module-list-item:after{content: ", "; }
.module-tags_cloud .module-list-item:last-child:after{content: " "; }

Thank you for any help you can give me.
