Align strikethrough support with GitHub Markdown#1548
Merged
Conversation
1. GitHub doesn't support `~word~` syntax for strikethrough, so we shouldn't either. 2. It's hard to make RDoc markup support `~~word~~` without supporting `~word~` as well due to the way attribute manager works. So instead we rollback the support added in #1541. Users can still use `<del>text</del>` syntax for strikethrough. 3. Fix `<code><del>text</del></code>` not rendering as `<del>text</del>` in HTML output. 4. Update documentation to reflect the new support.

question: Is this is a leftover from merge conflict?
