+ * annotate.el:
+
+ - fixed 'annotate-previous-annotation-ends'
+
+ 'annotate-previous-annotation-ends' scans the buffer contents
+ backward looking for an annotation before a buffer position
+ (let's' call this position 'POS').
+
+ If an annotation exists on 'POS' the backward search starts from a
+ position less than the starts of said annotation.
+
+ But unfortunately in the local function
+ 'annotate-previous-annotation-ends' the test to stop the searching
+ is wrong.
+
+ This is the code for the local function:
+
+ ----
+
+ (cl-labels ((previous-annotation-ends (start)
+ (let ((annotation (annotate-annotation-at start)))
+ (while (and (/= start (point-min))
+ (null annotation))
+ (setf start (previous-overlay-change start))
+ (setf annotation (annotate-annotation-at start)))
+ annotation))))
+
+ ----
+
+ Let's assume that the annotation under 'POS' starts at
+ (point-min), of course this is the first annotation of the buffer
+ and the function should returns nil.
+
+ Then the initial value of 'start' (argument of the local function
+ above) is one less the starting of the annotation under 'POS' and
+ -in this case- values 0 (when '(point-min)' values 1) no
+ annotations can exist at 0 and, moreover, (/= start (point-min))
+ is non nil; therefore the test passes and the results of the
+ function is the annotation under the position 'start' where
+ 'start' get the value of (previous-overlay-change start)).
+
+ The latter expression '(previous-overlay-change start)' return the
+ position in the buffer where there is a change in an overlay or
+ (point-min) if no change in overlay exists; in the case under
+ examination the expression returns (point-min) as the annotation
+ under 'POS' is the first in the buffer.
+
+ In conclusion, the function returns the annotation under 'POS' as
+ the annotation that supposed to starts before the annotation under
+ 'POS', instead of nil!
+
+ To reproduce the bug:
+
+ buffer contents
+ ****
+ ****
+ ^^^
+ annotate this portion of the buffer
+
+ ****
+ *aaa
+
+ then annotate all the non-annotated text.
+
+ AAAA
+ Aaaa
+
+ The coloring of the highlight of the two annotation will be the
+ same (wrong) while the background color of the annotation text is
+ not (which is correct).
