Or 272 (34 columns), if we're talking the first example. Right?

All right, thanks. So, this time I ended up increasing the window width 
by 1 pixel, and wrapping disappeared. The widths in pixels:

288 total, 272 body: text is wrapped.

289 total, 273 body: no wrapping.

Ok, but that doesn't seems to make much of a difference: I have the 
frame maximized when experimenting with this (although that's not 
required to reproduce the problem), and there are only two windows.
