test: refactor and update tests

test: whitespace and mininit

This removes tests for one awful corner case: if you have in a single
file both expressions `/(\d)/` and `/\d*(\d)/`, the second pattern's
regexplanation will *sometimes* erroneously repeat the heading "capture
group 1", but you can clear this up by hovering a different regexp first

This case is weird enough that I'm choosing to ignore it for now
