[WIP] Default to ./ when no <src>

[valeriangalliat]

• See Change behavior when no src #347

So this is the simple version evoked here, where - is not a "special <src>", because it takes less code, and will be fine for 99.9% usages.
#350 needs to be merged first.

What's left

• Make a default exclude pattern, for example taken from .gitignore, to not document sylesheets from vendor directories like node_modules.
• Could also exclude destination directory, even if it's not supposed to contain documented Sass files.

Coverage remained the same at 91.23% when pulling 9db90d6 on behavior-no-src-simple into 133057d on develop.

It's so simple and clean it could be added to 2.0 ?

Which means no more cat file.scss | sassdoc - src/ ?
Which I totally fine with. I find it confusing.

Why not. @hugogiraudel?

Yep.

Which I totally fine with. I find it confusing.

Alright, it's really an edge case to me anyway.

Eveyrthing fine with me folks.

[valeriangalliat]

Well while I think of it there's still issues about using ./, by default or not; if there's a node_modules or any kind of vendor directory, all Sass files in it will be documented too, and it's not what we want. We would need some kind of default exclude, from .gitignore for example.

Let's not merge this incomplete feature for 2.0. There's still stuff to be done with default exclude patterns.

[KittyGiraudel]

Okay. We'll see in 3.0 if it still makes sense.
