Asset pipeline - combining sets

[James Crowley]

I could be misunderstanding something in the docs, but it says that I
should be able to do this:

combine jquery,jquery-ui,jquery-validate as jquery-combination

However, I get an ArgumentNullException (stack trace below). It works
fine if I use combine with explicit filenames instead of other sets.
Having compiled the source code, I see this:

_graph.ForCombinations((name, assetNames) =>
{
var mimeType = MimeType.MimeTypeByFileName(assetNames.First());
_cache.AddFilesToCandidate(mimeType, name,
assetNames.Select(x => _pipeline.Find(x)));
});

with mimeType coming as null (because the assetNames don't have file
extensions) when it tries to then insert this in the cache. Is this
expected?

Thanks

Sigh.  Can you go log an issue on this?  

Assets needs more love.

Done :)

Can I also request support for multiple mime types per combination or
set? For instance, I might want to package up a bunch of JS file and a
related CSS file? And leave it to the asset pipeline to worry about
including both sets of files?
