Empty single quote strings are visible in the editor but not the codex frontend

[nkuttler]

Example ​http://codex.wordpress.org/Function_Reference/wp_list_pages , same on all other pages I checked.

Btw, the bug seems to happen when %%% is used, e.g. ​http://codex.wordpress.org/index.php?title=Function_Reference/wp_list_pages&action=edit&section=3 vs ​http://codex.wordpress.org/index.php?title=Function_Reference/wp_page_menu&action=edit&section=3

Double single quote strings is wiki-markup for italics. If you need to have code in the wiki with items in it like this, wrap it in <pre></pre> code to prevent wiki markup from being used.

I don't think <pre> works in the context that @nkuttler is referring to. When putting it inside the Usage template %%% block, the <pre> is displayed. When putting the <pre> outside the %%% block, the codes for the %%% template are expanded and displayed as well. Quite ugly.

Escaping with !'' doesn't work, and surprisingly entity escaping eg with &prime;' doesn't work either.

And heh, it does appear that the escaping trick DOES work here in Trac...just not in Codex...

Replying to tomauger:

When putting it inside the Usage template %%% block, the <pre> is displayed. When putting the <pre> outside the %%% block, the codes for the %%% template are expanded and displayed as well.

The workaround is to avoid %%% at all, replacing it with <pre>:

Yes, just use the pre HTML, not the %%% markup.
