experimental replacements for git checkout

The git checkout command has two forms. Since git 2.23 there are two experimental separte commands for each form.

• git restore
• replaces git checkout <path> to restore specific files to the current working directory. Examples of old/new equivalents:
• git checkout ac36590 hamburger.md
• git restore -s ac36590 hamburger.md
  # -s (or --source) commit or branch

• git checkout -- tiramisu.md
• git restore tiramisu.md
  # restore from index
•  
•  other interesting options
• --staged: restore to index
• --staged --worktree: restore to index and working directory
•  git switch
• replaces git checkout to switch to another branch. Examples of old/new equivalents:
• git checkout feature
• git switch feature

• git checkout -b newFeature
• git switch -c newFeature # -c or --create
