This looks pretty much like the lambda construct in Pike. Try to set
c-lambda-key to something that matches the "function" token and it
might work better.


That seems to have done the trick, thanks for the suggestion!

(If there are only small issues like this, it'd be simple to add
support for javascript. The big problem is that linebreaks are
relevant in some cases if I'm not mistaken, and those are consistently
ignored by all the recognition code.)


There are some edge cases where line breaks interact with "automatic semicolon insertion" in a way that makes them significant. But if you're not ending each statement with a semicolon you'll confuse cc-mode anyway, something I've come to regard as a feature.

Slightly off the original topic, cc-mode also has issues with if statements at the top level, such as...

1: if (1)        //topmost-intro
2:    f();       //func-decl-cont
3: else          //topmost-intro
4: g();          //topmost-intro-cont

vs.

1: function q()  //topmost-intro
2: {             //inline-open
3:     if (1)    //defun-block-intro
4:         f();  //substatement
5:     else      //else-clause
6:         g();  //substatement
7: }

These aren't all that common in my code, so it's easy to fix them up by hand. Some of the keywords are wrong as well, but modulo these issues cc-mode is quite capable of indenting the kind of JavaScript I write.
