@ -813,12 +813,14 @@ If DEFAULTS is a list of strings, the first element is the
default return value, but all the elements are accessible
using the history command \\<minibuffer-local-map>\\[next-history-element].
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
element of HISTORY (if specified) or `regexp-history'.
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.
