D7 sites with "tableofcontents" module generate IDs which preserve case, and replace spaces with underscores. This module generates IDs which convert to lower case and replace spaces with hyphens. Sites migrated from D7 may have numerous internal links to the "tableofcontents" style IDs.
Provide an option for toc_api to generate IDs consistent with those generated by D7 "tableofcontents" module so that internal links in migrated content still work.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
I think the latest patch is basically usable and we have used in production for over a year, so setting to needs review. There are edge cases where it will not do everything a user wants, but that is not a bug.
