Fix in_super-reliant msftidy checks

The conversion from hard tabs to two-space soft tabs broke a few checks.

```
wvu@kharak:~/metasploit-framework:master$ tools/msftidy.rb modules | grep ERROR | grep -v datastore
wvu@kharak:~/metasploit-framework:master$ git checkout -q beug/in_super && !!
git checkout -q beug/in_super && tools/msftidy.rb modules/ | grep ERROR | grep -v datastore
modules/auxiliary/admin/cisco/cisco_secure_acs_bypass.rb - [ERROR] '<' is a bad character in module title.
[snip]
wvu@kharak:~/metasploit-framework:beug/in_super$ 
```

- [ ] Run ```tools/msftidy.rb modules | grep ERROR | grep -v datastore```
- [ ] See no errors
- [ ] Check out the topic branch
- [ ] Run ```msftidy``` again
- [ ] Verify that there are errors

The test above accounts for only ```check_badchars```. You can test ```check_ref_identifiers``` using the following method:

```
wvu@kharak:~/metasploit-framework:master$ tools/msftidy.rb modules/exploits/windows/misc/hp_dataprotector_traversal.rb
wvu@kharak:~/metasploit-framework:master$ git checkout -b dev -t master
Branch dev set up to track local branch master.
