fetch: reduce duplicate in ref update status lines with placeholder
In the "remote -> local" line, if either ref is a substring of the other, the common part in the other string is replaced with "*". For example abc -> origin/abc refs/pull/123/head -> pull/123 become abc -> origin/* refs/*/head -> pull/123 Activated with fetch.output=compact. For the record, this output is not perfect. A single giant ref can push all refs very far to the right and likely be wrapped around. We may have a few options: - exclude these long lines smarter - break the line after "->", exclude it from column width calculation - implement a new format, { -> origin/}foo, which makes the problem go away at the cost of a bit harder to read - reverse all the arrows so we have "* <- looong-ref", again still hard to read.
