…unction And call this new helper function from both wrappedConfirmationFunction and wrappedPromptConfirmationFunction; this gives us more flexibility to do different things in each of those.
Previously it was used both for the Confirm handler and the Cancel handler, as well as for the Confirm handler of confirmation popups (not prompts). There was no other way to do it given how wrappedConfirmationFunction was shared between all these; but now there is. The logic is really only needed for the Confirm handler of prompts. This doesn't fix anything, it just makes things clearer.
The comment was apparently copy/pasted from above; the branch name cannot be blank in this case.
Most of our prompts don't (shouldn't) allow empty input, but most callers didn't check, and would run into cryptic errors when the user pressed enter at an empty prompt (e.g. when creating a new branch). Now we simply don't allow hitting enter in this case, and show an error toast instead. This behavior is opt-out, because there are a few cases where empty input is supported (e.g. creating a stash).
As of the previous commit, branchName can no longer be empty, so no need to handle this.
This doesn't really solve a pressing problem, because I guess it's unlikely that users add spaces at the beginning or end of what they type into a prompt; but it could happen, and in this case we almost always want to strip it. Just adding this here for completeness while I was working on this code. The only exception is the input prompt of custom commands, because who knows what users want to use that input for in their custom command.
The prompt code takes care of this now.

Remove unnecessary error checks: - forkUsername needn't be checked because as of PR jesseduffield#5043, the result of a Prompt call can no longer be an empty string - if the originUrl is empty for some reason, this will be caught by the "unsupported or invalid remote URL" error check below, which is good enough for this very unlikely case.
