[23/32] builtin/ls-tree: Let the oid determine the output algorithm

Commit Message

Eric W. Biederman Sept. 8, 2023, 11:10 p.m. UTC

Update cmd_ls_tree to call get_oid_with_context and pass
GET_OID_UNTRANSLATED instead of calling the simpler repo_get_oid.

This implments in ls-tree the behavior that asking to display a sha1
hash displays the corrresponding sha1 encoded object and asking to
display a sha256 hash displayes the corresponding sha256 encoded
object.

This is useful for testing the conversion of an object to an
equivlanet object encoded with a different hash function.
