int Loyc.Syntax.IIndexPositionMapper.LineToIndex ( int  lineNo)

Returns the index in a source file of the beginning of the specified line, where the first line is number 1, not 0.

If lineNo is zero, this method should return -1 (signifying an unknown location). If lineNo is larger than the largest line number, this method should return the index of end-of-file.

Implemented in Loyc.Syntax.IndexPositionMapper< CharSource >, Loyc.Syntax.SourceFileWithLineRemaps, and Loyc.Syntax.EmptySourceFile.
