Bug#506658: vim-tiny: Tabstop positions calculated incorrectly for values other than 1, 2 and 4

[TIguana]

Package: vim-tiny
Version: 1:7.1.314-3+lenny2
Severity: normal


Text will be displayed at a column position less than the position where it
should be displayed, when line numbers are enabled using ":se nu", unless
the tabstop position is one of {1, 2, 4}.

To reproduce the bug, type the following:

  echo -e \\ta | vim -u NONE -U NONE "+se nu" "+se ts=3" -

After vim has started, type the following (omitting the leading spaces):

  $a1

The cursor should now be at the "1", but in fact the "1" is displayed three
positions to the left of the cursor.
