Nested groups leave unexpected input in remaining to parse

[merc1031]

Expectation with scenario 1 is that the remaining to parse string does not container either of the / as they should be consumed by the outer group.

use nom::error::ErrorKind;
use nom_regex::str::re_captures;
fn main() {
  println!("{}", "Broken / still in remaining to parse");
  let re = regex::Regex::new(r"^([/](.+)[/])").unwrap();
  let parser = re_captures::<(&str, ErrorKind)>(re);
  println!("{:?}",  parser("/pr[]-/ && abc"));

  println!("{}", "Works but needs post processing");
  let re = regex::Regex::new(r"^([/].+[/])").unwrap();
  let parser = re_captures::<(&str, ErrorKind)>(re);
  println!("{:?}",  parser("/pr[]-/ && abc"));

  println!("{}", "/ still in remaining to parse");
  let re = regex::Regex::new(r"^[/](.+)[/]").unwrap();
  let parser = re_captures::<(&str, ErrorKind)>(re);
  println!("{:?}",  parser("/pr[]-/ && abc"));

}
