SingularityViewer/indra/llui/llscrolllistctrl.cpp
Lirusaito 61beedd3d9 Changed style of comments with asterisks to avoid highlighting errors on //* with weak highlighters, change is to all files that could potentially break highlights 
Most were needed, though some were just for possible problems with highlighting, should not affect performance whatsoever.
