Bug#691794: Pretty LSB logging overriden by plymouth

Package: lsb-base,plymouth
Followup-For: Bug #691794

He actually has a point.

This is related to #685437. But while, #685437 fixes the issue of
plymouth breaking pretty printing when it's not active (the kernel is
not booted with the slash parameter), I now noticed that when plymouth
is running at boot and I press "Home" on the keyboard to see the boot
messages, Pretty LSB logging is not taking place.

I have no idea how to fix this yet, tho'.
