There was never a requirement for etags to compute precise byte
positions for Emacs, mainly because source files get changed, and we
don't want users to have to re-run etags upon every change.  The
function 'etags-goto-tag-location' will look around that position in a
progressively-expanding window.  You will also see there that the
position in TAGS is interpreted as a character position, which already
introduces inaccuracies.

So etags is only required to produce approximately correct byte
positions, and it does that well enough.
