    The easiest way would be to use two passes. The first adds a blank line before each header: 

    perl -ple"$_ = qq[\n] . $_ if /^*header/" infile >modified

    NB! Different quotes on *nix!

    The second pass is just which ever of the earlier answers you like best.

    If I understand your problem, I can solve it! Of course, the same can be said for you.
