builtin-fast-export.c: fix crash on tagged trees
If a tag object points to a tree (or another unhandled type), the commit- pointer is left uninitialized and later dereferenced. This patch adds a default case to the switch that issues a warning and skips the object. Signed-off-by: Erik Faye-Lund <kusmabite@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
