merging results from completion-at-point-functions

[Eric S Fraga]

Hello all,

I currently use '(cape-dabbrev cape-ispell cape-dict) as the list for
completion-at-point-functions when writing prose.

I keep trying different orderings of these entries as the behaviour
changes significantly, not surprisingly given the /greedy/ nature of
completing-at-point, if I understand things correctly.  Ideally, I would
like a merged search for potential completions, such as I believe
company-mode does if you group backends.

Is it possible to specify a grouping or merge operation?  Or is there a
generalised capf that does this, I guess?

Thank you,
eric
