| 1885 | * |
| 1886 | * The "got" parameter is the URL that curl reported to us as where we ended |

| 1891 | * Our basic strategy is to compare "base" and "asked" to find the bits |
| 1892 | * specific to our request. We then strip those bits off of "got" to yield the |
| 1893 | * new base. So for example, if our base is "http://example.com/foo.git", |
