Subject: [PATCH] tde_create_translated_desktop: Instead of preprocessing the
 desktop file for use with intltool-merge already in the configuration phase,
 prepare the file during the custom command call just before calling
 intltool-merge. This will allow the natural use of the macro with the
 generated files.
