Don't split on ellipses

[waldyrious]

I believe it's not safe to always split sentences on ellipses. For example, the following sentence (initially mentioned at DavidAnson/markdownlint#719 (comment)):

Pausing... for... thought... should not [trigger splitting].

...currently splits as

'Pausing...',
'for...',
'thought...',
'should not [trigger splitting]'

but should remain as a single sentence.

Hey, I extracted this whole rule into a different repo - https://github.com/aepfli/markdownlint-rule-max-one-sentence-per-line

and within the test, it clearly states that theoretically, you could add ... to the ignore_words - we do not have any kind of fancy logic in there to detect sentences. We commonly only detect certain chars (or combinations) and split on those. That is also the reason why I renamed my liniting rule to max-one-sentence-per-line. This way, I removed the need to combine split sentences, etc. - https://github.com/aepfli/markdownlint-rule-max-one-sentence-per-line/blob/main/test/sentences-per-line.md - is my updated version of the test
