    [documentation]: Drop stale ms content.
    
    Drop claim about VS register being capped at 40,000 for backward
    compatibility.  I can find no evidence in the s.tmac commit history
    (with --follow) of this ever being true.  The corresponding request
    logic for .vs in env.cpp:vertical_spacing() similarly has no such check.
    
    Also, I tested it, with 39999, 40000, 40001, and 80000.  It works as you
    would expect (with the division by 10000 as already documented).
    
    Drop notice about formerly-provided .Ds and .De macros for X11 macro
    compatibility.  15+ years is enough warning.
