[C++ PATCH] config-lang.in

gtfiles in config-lang.in is a massive line of confusion.  While very 
rarely modified, it's completely impossible^W^Wreally hard to tell 
what's changed.

Committed this patch to break the line and sort it.  Although sh can 
cope with newlines in the middle of a string, the value gets fed to 
make, which doesn't understand.  Hence the escaped newlines.
