Replacing random paragraph endings in text

[jp91306]

I have a GROUP of LARGE documents that were improperly formatted so they contain paragraph breaks in random places where they should not. I have figured out that almost all of them occur where there is a lower case letter preceeding the error. So searching for [a-z]^13 finds them. But replacing the paragraph character with a space also deletes the preceeding character, so that doesn’t help. I need a way to find and replace only the paragraph character without deleting the preceeding (correct) character.
If I could FIND, move forward one character and then replace, that should work. I don’t know how to do that except manually, and that would take months.
Any ideas?
Thank you.
