XTerm Double-Width Display Issue

[顔無し]

Hello, all.  I recently upgraded to the latest version of XTerm (from 325-1 to 
326-1) and immediately noticed what seems to be a display bug involving 
double-width characters.  Single-width spaces are inserted after every 
double-width character when certain display events occur (e.g. the XTerm window 
losing focus).  I have attached two screenshots in hopes of demonstrating this 
bug.  Has anyone else experienced this?

For your convenience, here are some double-width characters:

その昔、武士と通人は「もり」、町人は「かけ」を好み、百姓は「饂飩」と定まっていたという話があります。

If you are using 326-1, try selecting the text by mouse.  Try maximizing and 
then unmaximizing your XTerm window.  Does the spacing change?

Thank you.
