Assuming these lines start a new paragraph, you could just use Find/Replace, where:
Find = ^p |Z
Replace = ^pZR
followed by:
Find = |
Replace = nothing
If you need to also eliminate any unwanted duplicate spaces, you could use
Find = ^w
Replace = ^32
Of course, all three Find/Replace operations could be recorded as a macro.
