Have you read Elisp info? This section describes about
"&optional" argument list.
12.2.3 Other Features of Argument Lists
---------------------------------------
[...]
If actual arguments for the optional and rest variables are omitted,
then they always default to `nil'. There is no way for the function to
distinguish between an explicit argument of `nil' and an omitted
argument. However, the body of the function is free to consider `nil'
an abbreviation for some other meaningful value. This is what
`substring' does; `nil' as the third argument to `substring' means to
use the length of the string supplied.
