irrlicht/source/Irrlicht/CLWOMeshFileLoader.cpp
cutealien 7d2dbdd0c8 Unify & improve log messages 
Lots of places where coders did not realize our Printer::log with hint adds a ": " string between message and hint
Which caused uglier messages in a few places (added documentation for that, maybe helps?)
Some added info in a few places
Some whitespace unification
Some spelling unification
