Show autocomplete even when cursor is placed within text

[ComFreek]

Currently, if the cursor is placed after punctutation (e.g. a bracket), autocomplete works:

But it doesn't if the cursor is right after a normal alphabet character:

For instance, this is a bit of a hassle if you write substitutions like f⟬γ⟭.

autocomplete uses a default IntelliJ-API-component, which is intended for... well, actual autocomplete, via a list that links e.g. "jDD" to the declaration delimiter. Unfortunately, if you have an alphabetic character (like "a") before it, IntelliJ looks for autocompletions for "aj", which are... well, none ¯_(ツ)_/¯

I'm almost sure that can be changed but that requires digging into the API again, and... sigh... `:D
