Subject: [PATCH] installer: Sort items with 'string-locale<?'.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

That way "Österreich" comes before "Schweiz" in a German locale (or
pretty much any sane locale.)

* gnu/installer/newt/page.scm (run-listbox-selection-page)[sort-listbox-items]:
Use 'string-locale<?' instead of 'string<=?'.
