In Git, fsck operations can ignore known broken objects via the `fsck.skipList` configuration. This option expects a path to a file with the list of object names. When the configuration is specified without a path, an error message is printed, but the command continues as if the configuration was not set. Configuring `fsck.skipList` without a value is a misconfiguration so config parsing should be more strict and reject it. Update `git_fsck_config()` to no longer ignore misconfiguration of `fsck.skipList`. The same behavior is also present for `fetch.fsck.skipList` and `receive.fsck.skipList` so the configuration parsers for these are updated to ensure the related operations remain consistent. Signed-off-by: Justin Tobler <jltobler@xxxxxxxxx> --- This patch is a follow up to previous discussion in [1] regarding how a misconfigured `fsck.skipList` without a path is handled.
