In this particular case, it seems simpler to declare the code right and correct the manual. We have to clarify the manual anyway. The other option (to really count "replacements") would need further clarification of what counts as a "replacement".

Thanks, Roberto!! Counting matches instead of replacements IMHO is simpler to understand and use. It also provides an easy way to count how many times a given pattern occur in a string.
path= "/many/nested/directories"
_,n= path:gsub("/",{}) -- n counts "/" chars
