Is that Postscript? :-) Actually, the ^ is just part of the regular
expression. In this case, the configuration change arrises from the
"Letter" lines being earlier in the file than the "a4" lines (so I am
relying on the prepend).

Actually, it will still work because those two lines will always show up
at the beginning of the file.
