I've never seen the preceding semi-colon like that. It makes perfect sense, there are a lot of JavaScript coders these days coming from languages like Ruby and these people often don't use semi-colons, very smart advice to protect against that!

The preceding semi-colon is definitely a very smart advice. I also will have to try out jshint (I've been using jslint).

Adding a leading semicolon just in case seems like overly defensive programming to me. You ought to pick trustworthy tools. If your script concatenator doesn't work right, I think it's better to fail fast rather than let things quietly be half-broken all over the place.

  You ought to pick trustworthy tools. Many JavaScript snippets are made to be integrated and added by other people on their websites.

It doesn't even need to be a semicolon. It's also common to see a ! used for this purpose.
