When displaying each line, tabs are expanded if all of the
following tests are true:

if BinaryMode() == 0 and    // file must not be in binary mode
    Query(ExpandTabs) and   // ExpandTabs must be on
    CurrLineLen() < MAXLINELEN / 8 and  // 2000 in 4.0
    Query(TabWidth) and         // TabWidth must be > 0
    DisplayMode() != DISPLAY_HEX and    // no hex mode
    BufferType() != _SYSTEM_    // can't be a system buffer

All of these except the "line length" apply to the entire
buffer.  Given that, the only reasonable explanation I can
think of is that there is a stray character past column
1999.

But, since you say you delete the line, and still have the
problem, well, I'm not sure how this is happening.

Note that the line-length maximum (divided by 8) is less in
older versions of the editor, 255 in 2.5, and 1000 in either
2.8 or 3.0.
