Nexus does not interpret + signs at URLs correctly

See https://github.com/NuGet/Home/issues/3858 , I have the same issue. What I observe when calling NCR's Nexus installation:

```
> http://***.com/nexus/service/local/nuget/repo-name/Nuget.Name/1.2.3+09d6b7c
404 Path /Nuget.Name/1.2.3 09d6b7c/Nuget.Name-1.2.3 09d6b7c.nupkg not found in local storage of repository "Repository" [id=repo-name]
```

Note the `+` sign missing in the response. Now when I escape manually:

```
> http://***.com/nexus/service/local/nuget/repo-name/Nuget.Name/1.2.3%2B09d6b7c
[download offered]
```

According sources for simpletons like me like ( https://stackoverflow.com/a/2678602/577067 ), it seems to me that you should not replace + by space in the path component of URLs. You should present me with the NuGet package for the first query.

Until this is fixed, we can't use SemVer 2 with Nexus.
