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.
