Tabs versus Spaces in Source Code

[63q2o4i02 at sneakemail.com]

I use Edit Plus for all my text-editing needs.  With a simple
shift-alt-i it faintly displays all spaces as little dots and all tabs
as '>>' (but using the single ascii character instead).  I use tabs to
indent blocks, then if stuff within a block needs to be aligned (such
as if statements or dictionaries), I used spaces.  So this is mixing
tabs and spaces, but the indentation level is always tabs.
