Thanks Ken this is a good one.

People might be confused about the (?s) since it's not in the 
transcript docs- but it is in the PCRE docs. (?s) says the dot 
metacharacter  matches any character, including newlines. So for 
example:

put space & linefeed & "hello" & linefeed & tab & "world" & tab & space 
into t
put "|" & trim(t) & "|"
-- result is
|hello
	world|
