LOL.

Intransition: the amount of space shown by a tab is totally dependent on
the terminal used to display the text, and (unlike some terminal
parameters) there is no way for Ruby or any language to change it. I guess
the best thing you could do would be to implement a writer stream that
converted tabs to spaces.
