[TUHS] Fifth Edition Manual Restoration

[segaloco via TUHS]

So I decided to keep the momentum and have just finished the first pass of a Fifth Edition manual restoration based on the same process I used for 3B20 4.1:

There were a few pages missing from the extant PDF scan, at least as far as pages that were in both V4 and V6 sources, so those are handled by seeing how V5 source of the few programs compares to V6.  I'll note which pages required this in a second pass.

I've set my sights on V1 and V2 next, using V3's extant roff sources as a starting point, so more to come.
