"X more..." link is not translated in the document tree

To reproduce:

• set a wiki to the french language
• create a lot of top-level pages in the wiki, more than 15
• go on the homepage of the wiki, in the Pages tree gadget

Actual result

• at the end of the tree, "X more..." text is displayed, even if all the rest of the UI is in french (see screenshot)

Expected result

• the "more" link should be in french language
