What an unhelpful response.  Do you realize how such responses shoot
yourself (and us) in the foot by preventing well-meaning contributors
from fixing your bug reports?

I fixed the doc strings in all functions except perform-replace.  The
latter is clearly an internal function, and its doc string says so.
