##### SUMMARY
I want to be able to use a pure (non-regex) line with lineinfile. Without accidentally escaping or not escaping characters.

##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
lineinfile

##### ADDITIONAL INFORMATION

I have a line in a file which has lots of special characters. I want to use Ansible's lineinfile module.

Ansible's lineinfile module requires a regular expression, which means lots of escaping for me, and a role or playbook that is more difficult to read.

Could the module support a non-regex line too?

Example of problem regex (have fun escaping this one! - real world example):

```yaml
    lineinfile:
      path: /etc/apt/apt.conf.d/50unattended-upgrades
      regexp: '#         "${distro_id}:${distro_codename}-updates";'
      line: '         "${distro_id}:${distro_codename}-updates";'
```
if not b_new_line.endswith(b_linesep):
            b_new_line += b_linesep
        
        
        if regexp is None and match is None and not exact_line_match:
            
            if insertafter and insertafter != 'EOF':
                
                
                if b_lines and not b_lines[-1][-1:] in (b'\n', b'\r'):
                    b_lines[-1] = b_lines[-1] + b_linesep
                
                
                if len(b_lines) == index[1]:
                    if b_lines[index[1] - 1].rstrip(b'\r\n') != b_line:
                        b_lines.append(b_line + b_linesep)
                        msg = 'line added'
                        changed = True
                elif b_lines[index[1]].rstrip(b'\r\n') != b_line:
                    b_lines.insert(index[1], b_line + b_linesep)
                    msg = 'line added'
                    changed = True
            elif insertbefore and insertbefore != 'BOF':
                
                
                if index[1] <= 0:
                    if b_lines[index[1]].rstrip(b'\r\n') != b_line:
                        b_lines.insert(index[1], b_line + b_linesep)
                        msg = 'line added'
                        changed = True
