 @section How do I put a glyph as annotation in a buffer?
 Here is a solution that will insert the glyph annotation at the
 beginning of buffer:
 You can turn this to a function (that optionally prompts you for a file
 name), and inserts the glyph at @code{(point)} instead of
 @code{(point-min)}.

+@section @code{map-extents} won't traverse all of my extents!
+I tried to use @code{map-extents} to do an operation on all the extents
+in a region.  However, it seems to quit after processing a random number
+of extents.  Is it buggy?
+No.  The documentation of @code{map-extents} states that it will iterate
+across the extents as long as @var{function} returns @code{nil}.
+Unexperienced programmers often forget to return @code{nil} explicitly,
+which results in buggy code.  For instance, the following code is
+supposed to delete all the extents in a buffer, and issue as many
+@samp{fubar!} messages.
+@lisp
+(map-extents (lambda (ext ignore)
+(delete-extent ext)
+(message "fubar!")))
+@end lisp
+Instead, it will delete only the first extent, and stop right there --
+because @code{message} will return a non-nil value.  The correct code
+is:
+@lisp
+(map-extents (lambda (ext ignore)
+(delete-extent ext)
+(message "fubar!")
+nil))
