Up to the next tab stop, and tab stops are placed at every 8th
column. No more, no less.

Because that's the way it has been since time eternal. Every
terminal I have seen have had tab stops at every 8th column.
Every printer I have encountered does the same (if it supports
plain text ASCII, that is; EBCDIC printers is of course a
different matter, but Python doesn't support EBCDIC anyway).

The character code 91 (decimal) is by its very nature configurable
what it means. For instance, some years ago here in Sweden it
was popular to configure your display device to show it as a
capital letter A with diaresis. Yet, Python absolutely believes
that it is an opening square parenthesis.
The fact that some people are doing broken things (configuring
their editors to have tab stops at other than every 8th column)
is not enough for me to give up tabs. It is *their* problem if
they do such stupid things.
