added emacs binding to "Find assignments to this symbol"
fuzzy matching now works as intended

The cscope-adjust variable indicates whether the line number reported by cscope
should be the target of xcscope.el navigation operations, or whether a search
should be done around that line. Prior to this patch, this variable was
effectively always on, causing fuzzy searches even when they weren't desired
