possible issue with `update self` breaking choosenim (libcurl)
Working on an old Linux (Ubuntu 16.04) server I realized I had nim 1.2.x installed, so I checked if `choosenim` was available.

It was (couldn't check the version) so I tried

```bash
choosenim update self
...
   Updating choosenim
[##################################################] 100.0% 0kb/s
      Info: Updated choosenim to version 0.8.4
```

but then invoking choosenim:
```text
$ choosenim
could not load: libcurl.so(|.4)
(compile with -d:nimDebugDlOpen for more information)
```

(`sudo apt-get install libcurl4-gnutls-dev` fixed the problem, but I was intrigued by the fact that choosenim was working before the update, so it might be worth a check ...)
