spotting empty continuation lines2000-02-25 11:44:38Sometimes I'll receive a message with a header field where a continuation line is empty except for the indenting whitespace. I'd like to catch those in a recipe. The problem is that the newline before a properly indented continuation line in a header won't match procmail's $ or ^ (usually that's a good thing). * H ?? ? egrep '^[ ]+$' # egrep -x '[ ]+' if it groks -x will do it, but is there a way within procmail without the external program?
