doc: /* If non-nil, a function to call when printing unreadable objects.
By default, Emacs printing functions (like `prin1') print unreadable
objects as \"#<...>\", where \"...\" describes the object (for
instance, \"#<marker in no buffer>\"). If this variable is non-nil,
it should be a function which will be called to print the object instead.
instance, \"#<marker in no buffer>\").
The function will be called with two arguments: the object to be printed, and
the NOESCAPE flag (see `prin1-to-string'). If this function returns nil, the
object will be printed as usual. If it returns a string, that string
will then be printed. If the function returns anything else, the
object will not be printed. */);
