That sounds good, thanks.

The xu-* files are supposed to load correctly under both xetex and 8- 
bit (pdf)tex engines; at least that's how we use them in *latex  
formats, and I assume they'd work the same in plain-based formats. So  
it shouldn't be necessary to have two versions of these declarations.

The idea was that a single language.{def,dat} file should support  
both pdftex-based and xetex-based formats, avoiding the need to  
maintain parallel lang files for the different engines, or modify the  
file depending which format is about to be built.

(We may be revising the pattern-loading techniques in the next few  
weeks anyhow, as the current setup doesn't work to build these  
formats with the luatex engine.)
