71 g_object_unref() releases the memory of the InternetAddressList object
\r
72 returned by internet_address_list_parse_string() -- when last (only)
\r
73 reference is released, internet_address_list_finalize() will do cleanup.
\r
76 hmm, have to agree amdragon's "suggested alternative" is more robust
\r
77 (in maintainability point of view) than the one I took previously.
\r
79 The 3 other alternatives are not common in notmuch code and therefore dropped:
\r
80 1) use multiple goto labels to jump in
\r
81 2) use deeply nested if blocks
\r
82 3) the ultimate solution: do { .. } while (0) blocks and break;s >;)
