-If DEFAULTS is a non-nil symbol, then if `read-regexp-defaults-function'
-is non-nil, we use that in place of DEFAULTS in the following:
-  If DEFAULTS is the symbol `regexp-history-last', we use the first

-  If DEFAULTS is a function, we call it with no arguments and use
-  what it returns, which should be either nil, a string, or a list of strings.
+DEFAULTS can be a symbol.  If DEFAULTS is the symbol
+`regexp-history-last', we use the first element of HISTORY (if
+specified) or `regexp-history'.  If DEFAULTS is a symbol with a
+function definition, we call it with no arguments and use what it
+returns, which should be either nil, a string, or a list of
+strings.  Other symbol values for DEFAULTS are ignored.  If
+`read-regexp-defaults-function' is non-nil, its value is used
+instead of DEFAULTS in the two cases described in this paragraph.
 
 We append the standard values from `read-regexp-suggestions' to DEFAULTS
 before using it.
