(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

Skimming this thread, I think the conclusion here is that these
functions work as designed.  `C-x C--' reduces the size of the font in
the current buffer, but the "window body width" concept remains the
same.  (I.e., if you create a new buffer and display it, that's what
`window-body-width' is telling you the number of columns for.)

So I don't think there's anything to do here, and I'm closing this bug
report.
