I'm fairly sure I haven't touched anything which affects -j-safety.

The only content which has changed is to lose the mal-substituted origin
source files from DOC_MANx.  These caused unnecessary dependencies
between man$(1)-pages and the original source files, which have no rule
to trigger, and will be considered up to date.

All the properly substituted content in DOC_MANx is identical to what it
was before.  Other earlier lists were just intermediate processing
between the $(wildcard ) and the DOC_* lists, and are evaluated
immediately with :=.
