Can't clone from a bundle

[WelliSolutions]

Repro steps (Windows):

1. git init bundle-demo
2. cd bundle-demo
3. echo content>file.txt
4. git add file.txt
5. git commit -m "bundle demo content"
6. git bundle create ..\demo.bundle --all
7. Open SourceGit
8. Click on the "Clone remote repository" ☁ icon
9. Enter the bundle name as the repository URL

Result:
The remote URL is considered invalid.

Expected:
A repository can be cloned from a bundle, like we can clone it on command line.

Additional information:
Here's what it looks like on command line:

E:\>git clone e:\demo.bundle unbundled-name
Cloning into 'unbundled-name'...
Receiving objects: 100% (3/3), done.

Coming from Clone.cs, line 12, I find
ValidateRemote(), line 85, which calls IsValidURL(), Remote.cs, line 46. That accepts a few URL formats, line 25, none of which is a local file name.

Would we add a Regex allowing .*\.bundle? Or would we rather create a new button on the GUI handling bundles ("Clone from bundle"), maybe using a 📦 icon?

If you want to clone a local repo (include git bundle), the remote URL must match following formats:

• Use file:// protocol. For example: file://e:/demo.bundle
• Use relative path (Unix-like). For example: ./xxx.bundle, ../xxx/yyy.bundle

Will this work for Windows UNC paths, like \\Mothership\Projects\quick-xml (where Mothership is the name of my computer in local net and Projects is the shared folder)?

[love-linger]

Currently, Windows UNC paths does not supported by SourceGit.
