I don't know consult.  Is it a completion table?  For what?

I see.  A table where the candidates are the lines of a file.  Well, not
jarring the way I look at flex, not the way _I_ use it.  My personal
expectation is to bubble up the tightest matches to the top.  If you're
interested where I picked up the idea, it's from many years of Common
Lisp programming with lots (close to a million IIRC) of named symbols.

Anyway, sounds like a job for a flex-sort-but-only-sometimes completion
style.  Or a flex sorting algorithm with another formula that produces
more ties.

Then, in a file with these 5 lines:

1: fabricate organic ornitopters
2: bar
3: and also using fooey
4: baz
5: using foo

With the pattern "foo", my personal expectation, and the way flex works
right now IINM, is to see 5, 3, 1.

Do you prefer to see 3, 5, 1?  Or keep 1, 3, 5 as presumably the table
stipulates?  Or something else?  Probably your decision in a new 'omar
style.
