-// A LineHist records the history of the file input stack, which maps the virtual line number,
-// an incrementing count of lines processed in any input file and typically named lineno,
-// to a stack of file:line pairs showing the path of inclusions that led to that position.
-// The first line directive (//line in Go, #line in assembly) is treated as pushing
-// a new entry on the stack, so that errors can report both the actual and translated
-// line number.
-//
-// In typical use, the virtual lineno begins at 1, and file line numbers also begin at 1,
-// but the only requirements placed upon the numbers by this code are:
-//	- calls to Push, Update, and Pop must be monotonically increasing in lineno
-//	- except as specified by those methods, virtual and file line number increase
-//	  together, so that given (only) calls Push(10, "x.go", 1) and Pop(15),
-//	  virtual line 12 corresponds to x.go line 3.
