Implement advance-branches for jj commit
## Feature Description If enabled in the user or repository settings, the local branches pointing to the parents of the revision targeted by `jj commit` will be advanced to the newly created commit. Support for `jj new` will be added in a future change. This behavior can be enabled by default for all branches by setting the following in the config.toml: ``` [experimental-advance-branches] enabled-branches = ["glob:*"] ``` Specific branches can also be disabled: ``` [experimental-advance-branches] enabled-branches = ["glob:*"] disabled-branches = ["main"] ``` Branches that match a disabled pattern will not be advanced, even if they also match an enabled pattern. This implements feature request #2338.
