We can confirm the fix by showing that an onbranch config include will not cause a segfault when run outside a git repository. I've put this in t1309-early-config since it's related to the case added by 85fe0e800c (config: work around bug with includeif:onbranch and early config, 2019-07-31), though technically the issue was with read_very_early_config() and not read_early_config().
