@ -3262,9 +3262,10 @@ Fourth arg MUSTMATCH can take the following values:
input, but she needs to confirm her choice if she called
`minibuffer-complete' right before `minibuffer-complete-and-exit'
and the input is not an existing file.
- a function, which will be called with the input as the
argument. If the function returns a non-nil value, the
minibuffer is exited with that argument as the value.
- a function, which will be called with a single argument, the
input unquoted by `substitute-in-file-name', which see. If the
function returns a non-nil value, the minibuffer is exited with
that argument as the value.
- anything else behaves like t except that typing RET does not exit if it
does non-null completion.
