tablature fingering

[Hugh Myers]

Given the nature of the guitar fret board a note like a b may be
indicated in tablature in at least two ways. For instance in this
example:
\version "2.13.7"
upper = {
 \times 2/3 { e,8 [ e' b ] } \times 2/3 { gis8 [ e' b ] } \times 2/3 {
b [ e b ] }
}

lower = {
 s2.
}

{
 \time 3/4
 <<
 \new Staff \relative c'' {
   <<
     \new Voice = "1" { \voiceOne \upper }
     \new Voice = "2" { \voiceTwo \lower }
   >>
 }
 \new TabStaff \relative c' {
   <<
     \new TabVoice = "t1" { \voiceOne \upper }
     \new TabVoice = "t2" { \voiceTwo \lower }
   >>
 }
 >>
}

However what is wanted in ascii tablature at least is:

e--0--0--0-----------------------------------|
B---0--0--0----------------------------------|
G----1--4------------------------------------|
D-2------------------------------------------|
A--------------------------------------------|
E--------------------------------------------|

So how do I get from here to there?
