Even though the cat-file command with `-s` option does not complain when `--use-mailmap` option is given, the latter option is ignored. Compute the size of the object after replacing the idents and report it instead.
In order to make `-s` option honour the mailmap mechanism we have to read the contents of the commit/tag object. Make use of the call to `oid_object_info_extended()` to get the contents of the object and store in `buf`. `buf` is later freed in the function.
