I keep talking about it, but here it goes again: compare:
```
static Future<String> _getHeadRef(ObjectStore store, String branchName,
      String remoteBranchName) {

static Future<String> _getHeadRef(
    ObjectStore store, String branchName, String remoteBranchName) {

static Future<String> _getHeadRef(
    ObjectStore store, 
    String branchName,
    String remoteBranchName) {
```
and note how non-linear the eye movement is in the 1st case compared to 2nd and 3rd. It's not much, but things like this accumulate.
