How so? If everyone uses tabs exclusively, it wouldn't matter whether I
set my editor to display (or print filter to print) tab characters at
2,4,8 or 16 spaces, because anyone else can edit my file and have his or
her editor set to any other possible tab size, and _ALL_ the code will
line up properly. If, however, everyone uses spaces exlusively, one
author's (or the language author's *cough*) choice of _indent_ size is
imposed on everyone else. And I like to switch between 2,4 and 8 space
tabs (sometimes 6) just so the code _looks_ nice to me at that point and
I feel more comfortable editing it. But obviously this is better than
mixing tabs and spaces, as everyone seems to think.

Of course, when writing text which is to be _viewed_ (email, news,
READMEs), I always use ':set et' which expands tabs to spaces, but for
text to be _edited_ by others you would use tabs, for the reasons above.
But thanks for such insightful replies. I had forgotten Guido's style
guide existed, and thanks for pointing me to redent.py :)
PS. wrt printing, mpage is a really cool utility. Here are some of
the options I use for printing text:
mpage -s4 -W100 -L80
