I did a git bisect and came up with this:

| 3559ff84b244dae2109131507804b21126e0b07c is the first bad commit
| commit 3559ff84b244dae2109131507804b21126e0b07c
| Author: Bastien Guerry <bzg@altern.org>
| Date:   Thu Mar 20 17:07:03 2014 +0100

|     org-agenda.el: Fix bug when using `org-agenda-do-date-later' in filtered agendas
|     
|     * org-agenda.el (org-agenda-filter-hide-line): Hide from the
|     beginning of the line to the beginning of the next line.
|     (org-agenda-show-new-time): Use `move-beginning-of-line' and
|     `move-end-of-line'.
|     (org-agenda-drag-line-forward): Adapt to the new definition of
|     hidden filtered lines.
|     
|     Thanks to Igor Sosa Mayor for reporting this bug and to Nick Dokos
|     and Matt Lundin for providing further information.

Starting from release_8.2.5h-888-g798bb8d (this was latest as of this
morning) and reverting the above commit fixes Fletcher's problem.

Bastien, can you please take another look?

Thanks.
