However, even after the patch,
The example from the SO post differs from the result of Richie
Cotton's function...
The explanation is quite simple. In SO function, the first 1/3 quantile
of used example counts 6 points (of 19 in total), while
Sorry, I have seen it too late that we had different tab width in the original

Hm... we can read in the man page :

So this needs even more sophistication, using withCallingHandlers(.)
