   You can also use Lisp expressions to calculate parts of the
 replacement string.  To do this, write @samp{\,} followed by the
 expression in the replacement string.  Each replacement calculates the
-value of the expression, which ought to be a string, and uses it in
+value of the expression and converts it to text without quoting (if
+it's a string, this means using the string's contents), and uses it in
 the replacement string in place of the expression itself.  If the
 expression is a symbol, one space in the replacement string after the
-symbol name counts as part of the symbol name, so the value replaces
-them both.
