Go ahead and fill this in as: https://github.com/google/blockly/wiki/Lists#reversing-a-list

When you submit, also make a new issue to create this wiki content. We can probably make you an editor for the wiki and would greatly appreciate help adding the docs for your new blocks there.

Unless you find a Wikipedia or similar description of reversing a list. That would be good, too.

Until the wiki docs are created, this will not be sufficient for translators.

"tooltip - Short description for a block that reverses a copy of a list."

Blockly.Msg.LISTS_REVERSE_TOOLTIP = 'Reverse a copy of a list.';

/// grammar - Text that follows an ordinal number (a number that indicates
/// position relative to other numbers). In most languages, such text appears
/// before the number, so this should be blank. An exception is Hungarian.
