Feature Request: link and selected text to Markdown format

[huyz]

Like https://github.com/kawamataryo/copy-git-link for JetBrains, it would be nice if there would be an option to generate markdown that looks like this (code snippet included if text is selected):

[/somepackage/SomeClass.java#L42-L44](https://github.com/huyz/myrepo/blob/67b33efca188/somepackage/SomeClass.java#L42-L44)
```java
    public void setLast_name(String last_name) {
        this.last_name = last_name;
    }
```

    }

很棒的想法，利于CR，我支持了下。
