Many of the mailman based lists use [xxx] in the subject lines:
Subject: [iPAQ] a subject
or 
Subject: Re: [iPAQ] a subject

I have a rule and condition for both of these constructs:
	* ^Subject:.Re:.\[iPAQ\]
This matches the reply in the normal case. 

This works fine. Note that the left and right square brackets must be 
escaped.
The problem is when I get a subject such as:
Subject: Re: [Gpe] Re: [iPAQ] GPE - GNU PDA Environment


My condition for that should match is:
	* ^Subject:*\[iPAQ\]

Note that the leading asterisk is a flag to procmail, so the RE passed to 
egrep would be:
"^Subject:*\[iPAQ\]"

I have not tested this by manually running egrep, but it should work. 
What this ERE shoudl mean is:
The line starts with "Subject:" followed by 0 or more characters until the 
'[iPAQ]'.

It's got to be something so simple, what am I missing. I've been doing REs 
and EREs for 20 years.
