Features
- posh-git: parse environment variable (3ded4c0)
BREAKING CHANGES
- posh-git: this removes the posh-git segment. To mitigate,
rename the posh-git segment to git.
In case you had a custom template, make sure to migrate to the git
segment's template. You can now also leverage the same logic and
properties as the git segment in both the text template and/or
color templates.
