Apparently that's something that everybody "just knows" so it
doesn't need to go in the man page. :)

It is, however, in the 'info' page:

   The s' Command
   ===============
   
      The syntax of the s' (as in substitute) command is
   s/REGEXP/REPLACEMENT/FLAGS'.  The /' characters may be
   uniformly replaced by any other single character within any
   given s' command. The /' character (or whatever other character
   is used in its stead) can appear in the REGEXP or REPLACEMENT
   only if it is preceded by a \' character.
