This works if you use recent version of matplotlib with preview mode
on. Without the preview mode (or other similar ways to report the
dimension of the text from TeX side), I don't think this can be done.

This does not. First of all, "~" and "\mbox" are not supported if
usetex=False and I guess never will be. On the other hand,
as far as I can see, the whitespace stripping is not done in mpl
side. And I have a feeling that it may be the freetype library. mpl
uses FT_Glyph_Get_CBox to calculate the extents of the text and I
think this seems to fail when there is a trailing spaces. This is
beyond me I hope other developers have better idea.
So, Christopher,
I guess your best chance is to upgrade and use preview mode, or use
annotate function.
