UNEVALLED means pass the list of unevaluated arguments
`prompt' says how to read arguments for an interactive call.
- This can be zero or a C string.
- Zero means that interactive calls are not allowed.
- A string is interpreted in a hairy way:
- it should contain one line for each argument to be read, terminated by \n.
- The first character of the line controls the type of parsing:
- s -- read a string.
- S -- read a symbol.
- k -- read a key sequence and return it as a string.
- a -- read a function name (symbol) with completion.
- C -- read a command name (symbol) with completion.
- v -- read a variable name (symbol) with completion.
- b -- read a buffer name (a string) with completion.
- B -- buffer name, may be existing buffer or may not be.
- f -- read a file name, file must exist.
- F -- read a file name, file need not exist.
- n -- read a number.
- c -- read a character and return it as a number.
- p -- use the numeric value of the prefix argument.
- P -- use raw value of prefix - can be nil, -, (NUMBER) or NUMBER.
- x -- read a Lisp object from the minibuffer.
- X -- read a Lisp form from the minibuffer and use its value.
+ See the doc string for `interactive'.
A null string means call interactively with no arguments.
- `doc' is documentation for the user.
