3095 | # * 20 bytes representing the sha1 of a git commit | |

66ab84b9 | 3097 | # (except the last record, which can be overwritten) |

3102 | # viewing or editing (piped back through xxd -r), should the need | |
3103 | # ever arise. | |
3104 | # - The last record can be padding revision with an all-zero sha1 | |
