Option to allow quickSuggestions inside words

[aeschli]

quickSuggestions do not show up when typing in the middle of a word.
It would be great if that could be configured by the language (or even the user).

Languages with completion proposals that do not only insert but also replace the end of the symbol, can then enable this setting.

@jrieken Is it now possible to have quick suggestion in the middle of a word?

[jrieken]

Nope - in the sense of "it is still to annoying to do"

Ok, if we reopen this issue then? Just to clarify that it's not implemented yet. It's confusing right now as it's a dup of #32201 which says it's fixed (through #53945)
