Problem or use case

I want to create the branch from the bottom-right corner of the chat view. I usually give it a name, e.g. "new branch", and I don't care if characters are a valid git branch.

Proposed solution

Replace invalid characters (like spaces) with dashes.

Why this matters

This is a simple change that allows faster branch creation, less headache.

Smallest useful scope

Spaces are replaced by dashes.

Alternatives considered

An alternative would be marking the input field in red, saying "Invalid git branch name".

Risks or tradeoffs

Edge cases: trying to create a valid branch name with replacements, ends up with a invalid branch name.

• I would be open to helping implement this.

Something one might want to consider:

1. I create a branch "hello world"
2. The branch created is "hello-world"
3. Later I search for "hello w"

Even if I search with an space, the branch hello-world should appear as an option of an already created branch.

We couldl consider fuzzy finding, instead of replacing the space with the dash in the search. But this seems like a topic for a different PR.
