Change default initial branch to match github

[davisagli]

Fixes #59

Tested on my machine with and without init.defaultBranch set in ~/.gitconfig

[rohnsha0]

for me it still follows the ~/.gitconfig's defaultBranch

[davisagli]

@rohnsha0 Yes, that is my goal: use init.defaultBranch from ~/.gitconfig if it is set (because that is the user's explicit preference). But if it isn't specified there, then use main instead of master.

ummm, to my surprise. When I removed the init.defaultBranch it was still using the master branch... But looking it it again and wait for others to response!

main is more of a fallback than a default now.

Suggested change

	Use `main` as the default branch for new git repositories, unless it has been
	Use the `init.defaultBranch` setting in git `config` if available, else `main`, as the branch name for new git repositories. @davisagli

I have no idea how to run a local checkout of this branch to verify it works. It's not covered in the README, and I lack familiarity with the tooling. @davisagli can you clue me in?
