Attributes without values not being expanded

[typoon]

Hello,

I tried the following syntax, as in the emmet documentation, but the result is not as expected:
div[foo bar]

Expected:
<div foo="" bar=""></div>

Result:
<div></div>

Is this a bug or did I miss something?

Thanks!

The fix isn't totally correct. What happens now is:

div[foo bar] returns <div foo bar></div> when the expected would be <div foo="" bar=""></div>. Could you have a look?

Thanks!

Do you want to expand div[disabled] into <div disabled=""></div> ?

According to emmet's documentation, section Custom Attributes, that is the expected behaviour:

You don’t have to specify attribute values: td[colspan title] will produce 
<td colspan="" title=""> with tabstops inside each empty attribute 
(if your editor supports them).

Thinking about it, perhaps it would be nice to have some kind of configuration where I can define what attributes shouldn't have the ="" appended to it, as you made a really good point in the case of the disabled attribute.
I believe that by default all attributes should receive the ="", and the ones specified in the configuration array shouldn't, so we could have an array like ['disabled', 'selected'], that would cause these two attributes not to receive the ="" part.

What do you think?

OK, playground on docs.emmet.io seems to be same as your said.
