This patch adds missing % character escaping for custom git prompts
used in a few themes. It also includes escaping for git-prompt.sh.
In combination with CVE-2021-45444, this could allow code execution
when displaying branch information in cloned malicious git repositories.
However, zsh 5.8.1 and newer are largely the default zsh versions, and
on those supported distributions with older zsh versions, the CVE has been
found to be also patched.
For this reason, this doesn't qualify as a security patch, but a
bug fix for proper printing of git branches.
Fixes#4085: core -> plugin dependency issue.
Rename it to git_current_branch for clarity that it's git-specific.
Update all plugins that were calling it to use new name.
Fix variable leaks by making more variables in lib/git.zsh local.
Have lib/git.zsh use [[ ]] instead of [ ] everywhere.
