goimpl: inputRegex not match interface name expected

[yinheli]

https://github.com/golang/vscode-go/blob/master/src/goImpl.ts#L18

// Supports only passing interface, see TODO in implCursor to finish
const inputRegex = /^(\w+\ \*?\w+\ )?([\w./]+)$/;

// matched
t *MyFile io.Closer

// not matched
t *MyFile github.com/example/pkg/name-with-line/iox.FileAdapter

@stamblerre Can I try to fix this issue? Just modify the inputRegex ?

[stamblerre]

Sure, please give it a try if you would like to send a fix. Thanks!
