All three are valid, thanks.

The reference to cts_above_width is now inside the FEAT_PROP_POPUP part, and
the width is assigned rather than added to, so calling the function more than
once for a character cannot accumulate it.

The test width was indeed the problem: with 'columns' 80 the Tab size happens
to be right without the fix.  The test now uses NewWindow(10, 45) and fails
without the fix ("Expected 9 but got 4"), with only! added for the cleanup.
