Code:
sed '/^[-*]/{N;N;s/\(\n\)\([^ \t]*\)\(.*\n[^ \t]*[ \t]*\)\([^ \t]*[ \t]*[^ \t]*\)/\1\4\3\2/;}' infile

Catchy, and easy to remember Smilie

Thanks for that, Scrutinizer (and for sorting out the tags in my original post).

Working my way through the O'reilly Sed and Awk book at the moment - Aside from applying the knowledge gained to anything and everything I can, does anyone have any recommendations for resources following on from this?

Sorry for straying off-topic a little!
