A tab is *one* character. Your *editor* may show tabs visually
"expanded" or convert them to spaces. This is entirely editor dependent.
My current (python) editor, does expands tabs to the next *multiple* of 4.
It helps keep code aligned, and I have no need for 4 hard spaced tabs
without regards to alignment (yet). I have had editors that did 4 hard
spaced tabs, so it might be a developer/application preference.

... d = f.read()
>>> print repr(d)
>>> print d + 'goo'
>>> print repr(d + 'goo')
