-# Implementation notes for this file:
-#
-# 1) the 'id' form parameter is validated early on, and if it is not a valid
-# bugid an error will be reported, so it is OK for later code to simply check
-# for a defined form 'id' value, and it can assume a valid bugid.
-#
-# 2) If the 'id' form parameter is not defined (after the initial validation),
-# then we are processing multiple bugs, and @idlist will contain the ids.
-#
-# 3) If we are processing just the one id, then it is stored in @idlist for
-# later processing.
