# 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.
