postfix long lines lead to pflogsumm error message

Stefan `Sec` Zehl-5
On one of my machines my nightly pflogsumm report started to generate
lots of perl errors:

| Use of uninitialized value in length at /usr/local/bin/pflogsumm line 1472, <> line 1.
| Use of uninitialized value in substitution (s///) at /usr/local/bin/pflogsumm line 790, <> line 1.
| Use of uninitialized value in hash element at /usr/local/bin/pflogsumm line 792, <> line 1.

The offending log message looks like this:

May 14 01:54:26 ice postfix/smtp[40727]: A510E228BA: to=<[hidden email]>, orig_to=<[hidden email]>, relay=mx01.t-online.de[194.25.134.72]:25, delay=0.55, delays=0/0/0.19/0.36, dsn=5.7.0, status=bounced (host mx01.t-online.de[194.25.134.72] said: 550-5.7.0 Message considered as spam or virus, rejected 550-5.7.0 Message rejected because it was considered as spam.

The problem appears to be that the log message gets so long that postfix
omits the closing paren around the message, and pflogsumm expects it.

The question is, should postfix always keep the ")" at the end of these
lines, or should pflogsumm be fixed not to expect it? I can produce a
patch for both things if a consensus is found about this ;)

pflogsumm should not get confused.
