While I do not agree with _every_ style change, this will force Dokku to have consistent formatting across all shell scripts, which is arguably a Good Thing™.
The command used to reprocess everything is:
```shell
shfmt -l -bn -ci -i 2 -w .
```
This is useful in contexts where the repository directory may be created and interacted with via git-http-backend or other methods of updating a repository.
- add `report` and `set` subcommands to the git plugin
- move configuring the DOKKU_DEPLOY_BRANCH to the git plugin
- implement configurable GIT_REV support
- migrate DOKKU_DEPLOY_BRANCH settings
- add a golang-compatible, shell based method of setting plugin configuration variables
Deprecates the community dokku-git-rev plugin.
Closes#2621
Refs dokku-community/dokku-git-rev#9
Add forward slash cleanup of the app name for the git-upload-pack
command. Prevents is_valid_app_name from removing the application folder
on `git fetch`.
Git 2.11.0 breaks the git clone approach in git_build_app_repo() in
25ab004c53
git worktree is a much simpler approach but only works for git >= 2.5
so it is not available in Ubuntu 14.04.
Fixes#2512.
This trigger allows you to modify the contents of an application *after* it has been extracted from git/tarball but *before* the image source type is detected. For example, you may wish to autogenerate a Dockerfile based on some other application contents before detecting what type of build process - herokuish or docker file - to use.
