I tried this out, and I came across a certain issue: say you do
`C-h o foo TAB`, and then looking at the completion candidates
you realize you actually wanted something with `bar`, so you
type `M-DEL` to delete `foo` from the minibuffer to make room
for `bar`. But now `post-command-hook` runs with an empty
minibuffer before you start typing `bar`, so it updates the
completions buffer with a very large list of symbols, causing
Emacs to briefly stall. I think that the completions buffer
possibly shouldn't be updated when the minibuffer is empty.
Perhaps there could be a minimum minibuffer contents size for
updating the completions buffer, or some other heuristic to
avoid auto-displaying excessively large sets of candidates.
Another option is to update the completions buffer on
`post-self-insert-hook` instead of `post-command-hook`, that
way you only update the completions buffer when the user
actually inserts input in the minibuffer, and you don't need to
keep a `completions-no-auto-update-commands` list.
Best,
Eshel
