TYPO3 Core

In modulemenu.js is a check for top.fsMod.recentIds, and if there is a hit for the requested section, an id param is prepended to the params, but without a & to concatenate the other params.
This results in e.g. such a url when performing a live search:
http://localhost/typo3/sysext/list/mod1/db_list.php?id=6id=0&search_levels=4&search_field=test
which won't show any results.

How to reproduce: open list module and click on a page, then do a live search and click the "Show all"-Button.

Do the same from another module or the welcome screen, and you get all results.
