I thought selvage was either the finished edge of a piece of cloth, or the sewing of a cut edge of cloth to keep it from unraveling, whereas salvage is something "saved" from being disposed of. I'm sure of troy can enlighten.

Has anybody heard the asterisks lined up on the left edge of a comment in C, C++, or Java programs called selvage? I did, but think it was idiosyncratic to the program I heard utter it.
