them so they should now work as expected.
* New app: loadacm contributed by Peter Novodvorsky <petya@logic.ru>
for loading application character maps for working with Unicode fonts.
+ * sed now supports addresses (numeric or regexp, with negation) and
+ has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
+ * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
+ * Some cosmetic fixes to ls output formatting to make it behave more
+ like GNU ls.
