There's a minor 'catch' here, which may prove interesting. The
`character-classes' supported by the regexp engine of Emacs
consider the end of a line a [[:space:]] character, so you can do
replacements like:
\([[:space:]][pP][pP]\.\)[[:space:]]+\([0-9]+\) -> \1~\2
This will DTRT, as far as the original poster's question is
concerned, but it may `join' some lines in the process. A bit of
fill-paragraph can fix that too, and you are ready to go :-)
