Ctags is very VI specific.  The portion of each tag that takes the
editor to the right place in the code is a command for the ex program.
("Ex" is a part of VI originally it was a separate program but it isn't
in modern VI-like editors).  A valid Ctags program could put all sorts
of things in that field.  Instead Emacs uses the number of bytes from
the start of the code file.
