Subject: [pgjdbc/pgjdbc] issue #3635: Consider migrating from spaces to tabs

See

>i get approached by not one, but TWO coworkers who unfortunately are highly visually impaired,
and each has a different visual impairment

> * the other uses tab-width 8 and a really wide monitor

> * these guys are not just being fussy — it's almost surprising they can code at all, it's kind of sad to watch but also inspiring

Code with tabs consumes [fewer cells on braille displays](https://stitcher.io/blog/tabs-are-better).
Code with tabs consumes the same or bigger amount of tokens when using [ChatGPT 4o tokenizer](https://platform.openai.com/tokenizer). For the small files the number of tokens is more-or-less the same, and a bigger [TrieNode.kt](https://github.com/Kotlin/kotlinx.collections.immutable/blob/bd5ac10f1e3b72c8bd6335005bf27d751e0d8b5...) consumes 8958 tokens (32462 chars) with tabs, and it consumes 8859 tokens (37757 chars) which means 1% more LLM tokens when using tabs :-/

Of course, changing the spaces to tabs would be disruptive, however, it might bearable. I've not explored it yet.
However, it looks going with tabs is the right thing to do.
