completion double tab should show rest of the strings

[jcubic]

Expected behavior

If you have paths that you complete and you returning path + dir or path + file when press you double tab it should only show file or dir not whole text

Actual behavior

it show whole paths

Steps to reproduce

• open https://jcubic.github.io/git/
• clone jcubic/git repo
• type ls /git/.git
• press tab twice
• it echo: git/.git/ git/.github/ and it should display .git/ .github/

This is not possible because, common string will remove git/.git and completion code can't know about the context of paths, it would require new API maybe callback function that will be called with array of matched strings and user will be able to call echo on that array and remove what he things is correct.

[jcubic]

doubleTab: function(arr) {
   this.echo(arr.map(function(completion) {
       return completion.replace(/.*\/([^\/]+)\/?$/, '$1');
   }));
}

[jcubic]

the API look like this:

doubleTab: function(string, arr, echo_command) {
   echo_command();
   this.echo(arr.map(function(completion) {
       return completion.replace(/.*\/([^\/]+)\/?$/, '$1');
   }));
}

you don't need to call echo_command, if you don't want prompt + command like with normal completion.
