How's this?

item(tt(g:opts:))(
Expand words like the echo builtin when no options are given (tt(g::)).
With the tt(o) option, octal escapes don't take a leading zero.  With the
tt(c) option, sequences like `tt(^X)' are interpreted.  With the tt(e)
option, interprets `tt(\M-t)' and similar sequences like the print
builtin.  With both of the tt(o) and tt(e) options, behaves like the
print builtin except that in none of these modes is `tt(\c)' interpreted.
)

And this for s,

 separator var(string).  Note that a var(string) of two or more
 characters means that all of them must match in sequence; this differs from
 the treatment of two or more characters in the tt(IFS) parameter.
-See also the tt(=) flag and the tt(SH_WORD_SPLIT) option.
+See also the tt(=) flag and the tt(SH_WORD_SPLIT) option.  An empty
+string may also be given in which case every character will be a separate
+element.

Okay, I guess I don't really either.

${(/::) looks like an alien girl waving goodbye. :)
