For the regex novices here, would anyone mind explaining what that pattern is meant to match? More specifically, what `.(?:.=.*)` is meant to do?

It's meant to match any number of any characters, then match an equal sign, then match any number of any characters. But it's very badly written. It should instead simply be written

    .*=.*
BTW, your comment got mangled by HN's markdown formatting.

Gotcha - I thought I was just missing the point as to why it wasn't simpler since it looked to have been structured that way intentionally.
