Well, just as messy, but fixing your problems:

Use $ and ^ for what they're worth, rather than \n. Also always use
double escapes (\\) in regexes in macros, since there are two rounds
of escape processing: one for parsing the literal code to a string and
one more when parsing the string as a regex. (This is just the sort of
thing I'd like my single-quote patch incorporated for)

So you end up with something like:

    # Remove all extra spaces to the left
    replace_all("^\\s*", "", "regex")

    # Change blank lines to @@@@@
    replace_all("^$", "@@@@@", "regex")

    # Remove all line feeds
    replace_all("\\n", " ", "regex")

    # Now go back and replace any @@@@@ with dbl line feeds
    replace_all("@@@@@", "\\n\\n", "regex")

    # Clean up extra blank space to the right and left of text
    replace_all("^\\s*", "", "regex")
    replace_all("\\s*$", "", "regex")

If you don't need to handle indented paragraphs you can replace the
first two comands with:

    replace_all("^\\s*$", "@@@@@", "regex")
