Seacue,
I find that one can do quite complex things with creative use of search & replace.
For example, if there's leading space(s) on a line to be removed, replacing [Paragraph mark space(s)] with [Paragraph mark] will eliminate them (except for line 1, but that's not too taxing to do by hand!).
For Windows users, the GNU text tools are very useful for more complex text manipulation.
