Broken attribute highlighting when using tag name interpolation

[nkovacs]

- var tag='a'
// Broken
#{tag}(
    @click="doSomething", 
    :href="url",
)
// Broken
#{tag}(
    click="doSomething", 
    href="url",
)
// These work fine
a(
    @click="doSomething",
    :href="url",
)
a(
    click="doSomething",
    href="url",
)

Ok, so the issue seems to be with the interpolation subpattern having the same name:

language-pug/grammars/pug.cson

Line 1096 in f1f1610

name: "source.script.jade entity.name.tag.pug"

It looks like this prevents the tag_name pattern from ending correctly, because if I log the cursor scope at ( (with the cursor in front of it), it still says "source.script.jade entity.name.tag.pug", whereas without the interpolation, it says "constant.name.attribute.tag.pug".

Renaming it to "source.script.jade entity.name.tag.pug.interpolated" fixes the highlighting for the attributes (the tag name ends correctly at } now), but the highlighting of the interpolation doesn't work correctly (it doesn't seem to work that well anywhere else either).
