After a bit more reading of the manpage, you can actually do what you
want. There is only one *command* per line, but each command can have
several *functions*, and 's' is a function. You can use a
function-list by separating them with newlines and putting { } around
the whole thing. so
sed -e '/^Subject: /{ s/\[PHP3\] *//g
s/\[PHP4BETA] *//g
}'
will do what you want.
