Md to Md: Issue while converting to Reference Links, if file contains both Inline and Reference Link

I am trying to convert all links in a markdown file to Reference Links. 
Sometimes, the original file contains both Inline and Reference Link. e.g.

```markdown
- A **web app** is a [client--server] [computer program](
https://en.wikipedia.org/wiki/Computer_program "Computer program").

[client--server]: https://en.wikipedia.org/wiki/Client%E2%80%93server_model 
"Client–server model"
```

becomes
```markdown
- A **web app** is a \[client--server\] [computer program].

[client--server]: https://en.wikipedia.org/wiki/Client%E2%80%93server_model 
"Client–server model"
[computer program]: https://en.wikipedia.org/wiki/Computer_program "Computer 
program"
```

The issue comes when, I render it to HTML, and the `client--server` link in 
the above example doesn't work anymore, as the square brackets are escaped.

What do you suggest?

Thanks!

Temporarily, I am solving this issue by using the following python code  
(but there can be some false positives)

```python
import sys
import re

Pattern = '\\\\\[(.*?)\\\\\]' # Non greedy pattern # Refer: 1, 2
Output = re.sub(Pattern, '[\\1]', sys.stdin.read())
print(Output)
```

Try using

pandoc -t markdown-shortcut_reference_links --reference-links

Then you'll get:

-   A **web app** is a [client--server][] [computer program][].

  [client--server]: https://en.wikipedia.org/wiki/Client%E2%80%93server_model
    "Client–server model"
  [computer program]: https://en.wikipedia.org/wiki/Computer_program
    "Computer program"

It would be desirable to make pandoc smarter, so it
generates the output


-   A **web app** is a [client--server][] [computer program].

  [client--server]: https://en.wikipedia.org/wiki/Client%E2%80%93server_model
    "Client–server model"
  [computer program]: https://en.wikipedia.org/wiki/Computer_program
    "Computer program"

even without `-shortcut_reference_links`, and doesn't
escape the brackets.  (Just avoiding the escaping
would not work, because pandoc would treat

    [client-server] [computer program]

as a single reference link to the second URL.

In CommonMark we've tightened up reference links so
that there can't be a space between the two parts,
which helps avoid problems like this. We may want to
make the same change now in pandoc's markdown parser,
though I'm hesitant, as it might break some
existing documents.
