The link to the issue you mention is broken because the bootstrap repository moved from twitter to twbs. The new link is https://github.com/twbs/bootstrap/issues/3057. Also note, that ultimately regardless of personal semicolon preference, this was an issue because of a parsing bug in JSMin. It was fixed in JSMin with this commit[0]. Other minifiers such as Closure and YUI did not exhibit any issues with the code as it had been written. [0] https://github.com/douglascrockford/JSMin/commit/5ca277ea452...

It wasn't a "fragile edge case", it worked just fine with no ambiguity in every javascript implementation. The problem is that jsmin is a naive pile of textual replacements (though not quite as abysmal as John Gruber's markdown.pl) instead of being a javascript implementation — something that actually parses javascript into an AST and compiles it to minified javascript. He left out cases for several unary operators so it broke perfectly valid code. After bitching at them he came to his senses and fixed it: https://github.com/douglascrockford/JSMin/commit/5ca277ea452... Unless for some reason you need your minifier to be trivial enough to be portable with no dependencies, you should really be using something along the lines of google's Closure Compiler, which produces far better output and even has stuff like tests!
