And make this work.

<!-- build:css common.min.css?__inline=true -->
<link rel="stylesheet" href="foo.css"/>
<link rel="stylesheet" href="bar.css"/>
<!-- endbuild -->

↓

<link rel="stylesheet" href="common.min.css?__inline=true"/>

@sindresorhus your thought about this ?

[sindresorhus]

@stephanebachelier I don't have time or interest in reviewing things on this project, sorry. Feel free to merge PRs you think make sense.

[stephanebachelier]

@sindresorhus sorry I didn't see this comment before. Ignore my other comments :)

[sindresorhus]

@stephanebachelier No worries. And I really appreciate you stepping in. I'm just burned out by this project.

@weilao I can see some use case where a query parameter might be needed.
Can you add a test

[ValorLin]

@stephanebachelier
All done : )

ping @weilao
Could you squash and rebase on dev branch.
It might be easier to tweak the regexp to extract only the path instead of using an extra function.
