+This command honors the `yank-handled-properties' and
+`yank-excluded-properties' variables, and the `yank-handler' text
+property, as described below.

+Properties listed in `yank-handled-properties' are processed,
+then those listed in `yank-excluded-properties' are discarded.
+
+If STRING has a non-nil `yank-handler' property anywhere, the
+normal insert behavior is altered, and instead, for each contiguous
+segment of STRING that has a given value of the `yank-handler'
+property, that value is used as follows:
+
+The value of a `yank-handler' property must be a list of one to four
+elements, of the form (FUNCTION PARAM NOEXCLUDE UNDO).
+FUNCTION, if non-nil, should be a function of one argument (the
+ object to insert); FUNCTION is called instead of `insert'.
+PARAM, if present and non-nil, is passed to FUNCTION (to be handled
+ in whatever way is appropriate; e.g. if FUNCTION is `yank-rectangle',
+ PARAM may be a list of strings to insert as a rectangle).  If PARAM
+ is nil, then the current segment of STRING is used.
+If NOEXCLUDE is present and non-nil, the normal removal of
+ `yank-excluded-properties' is not performed; instead FUNCTION is
+ responsible for the removal.  This may be necessary if FUNCTION
+ adjusts point before or after inserting the object.
+UNDO, if present and non-nil, should be a function to be called
+ by `yank-pop' to undo the insertion of the current PARAM.  It is
+ given two arguments, the start and end of the region.  FUNCTION
+ may set `yank-undo-function' to override UNDO.
