Reformat method synopsis whitespaces

Hi Everyone, I'm looking for feedback with regard to my PR which reformats method synopses (https://github.com/php/phd/pull/38): Currently, we display function/method signatures without any line breaks, but with a lot of unnecessary spaces between parameters, as well as around the parameter list. See an example here: https://pasteboard.co/K4BXRuv.png My PR would add a line break for each parameter as well as remove any other unnecessary whitespaces. See https://pasteboard.co/K4BZNN9.png for example (but the linked PR has a few more images attached). I'm curious if anybody sees any issue with the new formatting? Class synopses look a bit weird, but I don't think it's worse than what we currently have. Regards: Máté
