Backslash and forward slash in some code end tags

[duianto]

Some files use a back and forward slash in all code end tags <\/code>.

But here's a file with a single backslash and forward slash <\/code> in the hint,
and only forward slashes </code> in the rest of the file:
https://github.com/twostraws/Unwrap/blob/52d0a7a9c19c6bb78b7ea8c168a18838bc4ccefd/Unwrap/Content/SixtySeconds/access-control.json

And here's a file with only forward slashes </code>:

A quick google search didn't turn up much,
for the difference between a back and forward slash <\/code>,
compared to just a forward slash </code>.
