It doesn't, sorry. I didn't realize that this could be an issue,
because I use an window manager which keeps frames full-size anyways.

But I spent the afternoon browsing the sources for a solution that
does. The two patches below seem to make it work (only slightly

Now, if an ASCII font was changed, Fset_fontset_font checks all frames
whether FONTSET is their frame fontset and forces a resizing of all
frames that have. This is done by the new function
x_new_fontset_force, which is like x_new_fontset, except that it does
its works even if new fontset = old fontset. (This is done by
factoring out a new function x_set_fontset_internal out of x_set_fontset.)
