This is a first step in removing die() calls from ref-filter formatting logic, so that it could be used by other commands that do not want to die during formatting process. die() calls related to bugs in code will not be touched in this patch. Everything would be the same for show_ref_array_item() users. But, if you want to deal with errors by your own, you could invoke format_ref_array_item(). It means that you need to print everything (the result and errors) on your side. This commit changes signature of format_ref_array_item() by adding return value and strbuf parameter for errors, and adjusts its callers. While at it, reduce the scope of the out-variable.
