    -- Definitions for units known to val
    -- File format is two strings and a return statement with them in it:
    -- string in quotes [=[ ... builtin_units ... ]=].
    -- string in quotes [=[ ... builtin_units_long_scale ... ]=].
    -- First string, builtin_units, is short-scale, second string is long scale.
    
    -- Entry format:
    -- One record per line, starting in first column, having 2-4 fields.
    -- Field separator: two or more spaces
    -- Between first and second fields: two or more spaces
    -- Between all other fields: two or more spaces, or one or more tabs
    -- Entries without two spaces in them are ignored.
    
    -- There must be a blank line before the first entry and after the last.
    -- I.e. the first two and last two characters of the string must be newlines.
    
    -- Format of entry. Two record types:
    --
    -- One record type is a wikilink:
    -- Unit-code        [[ pagename | Symbol-accepts-HTML-only ]]
    -- Text-field separator is still two spaces.  Two spaces not allowed in wikilink.
    --
    -- The other record type is all fields:
    -- Unit-code        symbol-accepts-HTML-only        pagename#section-OK
    --
    -- Plus there is an optional field that goes at the end after two or more spaces.
    -- Whether it is a number or an equation or the letters SI,
    -- any of these three has the same function: a wikitable sorting "scale".
    -- It is for sorting, and it works for either record type.
    -- Difference is SI can't accept HTML. But SI correctly scales any SI prefix.
    -- (Optional fields ALIAS and NOSPACE and ANGLE are for advanced users.)
    
    -- "Invalid unit" error:
    -- Using SI requires that the symbol equal unit-code, so never allows HTML.
    -- Any difference between SI or symbol must be an SI prefix, such as k, M, or G.
    -- A space at the end of an entry is an error. No space at each EOL.
