    All of them? Let's see.

    Is every option that is in the manual in its Variable Index? I'm guessing 
yes
    (modulo indexing bugs).

    Is every variable that is in the Variable Index an option? No; the second 
one
    listed, `abbrev-file-name', is a counter example.

    How many variables are there in the Variable Index? 786 (`M-x what-line' 
shows
    there are 795 lines, minus 9 for the intro text.)

    So if there are ~7000 options at startup time, maybe ~10% are in the manual.
    Yes, certainly far from all.

    Some options are no doubt documented in the Elisp manual, instead. But there
    there is no division of that index by object type (e.g. variable vs 
function),
    so there is no easy way that I'm aware of to count them.

My dexterity with the obvious aside, an unexpected lesson from this
thread is that I can learn a lot by browsing Customize.  Thank you,
fellas.
