 Substitute a string for a pattern in another string. Make sure there is
 enough room!

 This routine looks for pattern in s and replaces it with
 insert. It may do multiple replacements.

 Any of " ; ' $ or ` in the insert string are replaced with _
 if len==0 then the string cannot be extended. This is different from the old
 use of len==0 which was for no length checks to be done.
