Re: Troubleshoot recipe to prevent repeating footer

Actually, it might be working too well and preventing the footer from being
inserted.

Apparently it looks for the second line of the footer file, without anchors.
If the second line of the footer is blank, no message will ever get a footer.

YECCH.  Far better,

 TEXT=`sed -e1d -eq footer.txt`

|     :0 fbBw
|     * $ ! $\TEXT
|     | cat - footer.txt

At the least, make the condition

  * $ ! ()\<$\TEXT$

so that a hit prevents adding the footer only if it begins with the start of a
word and ends at the end of the line.
