BUG - RELEASE: Org-mode version 6.07

[Bernt Hansen <bernt@norang.ca>]

Hi Carsten,

I just upgraded to 6.07 this morning from 6.06b and org-cycle takes a
long time to finish when working on my org files.  My org file is
currently 26804 lines, 1134144 characters.

Release 6.06b does not have this issue.

I created a new task at the top under '* Tasks' as follows at the top of
my file

                ,----
                | * Tasks
                | ** TODO Do something
                |    [2008-09-19 Fri]
                |    check something
point here  --> | 
                | * Projects
                `----
                  <26798 more lines follow...>

and just hit tab when not on a heading line (ie on the blank line in the
body of the task 'Do something' right before '* Projects' and Emacs goes
away for a few seconds)

The following commit causes this behaviour:

,----

I'm moving back to the commit before this
(d6cabfc6b283b3e65ca87de45a30854b8facfe2e) for now since the delay is
too disruptive for me.

Let me know if there is anything else I can do to help isolate this
problem.

Thanks for a great tool!!

Regards,
Bernt

> Secondary filtering of agenda views.
> ------------------------------------
>
>     You can now easily and interactively filter an existing
>     agenda view with respect to a tag.  This command is executed
>     with the `/' key in the agenda.  You will be prompted for a
>     tag selection key, and all entries that do not contain or
>     inherit the corresponding tag will be hidden.  With a prefix
>     argument, the opposite filter is applied: entries that
>     do have the tag will be hidden.
>
>     This operation only /hides/ lines in the agenda buffer, it
>     does not remove them.  Changing the secondary filtering does
>     not require a new search and is very fast.
>
>     If you press TAB at the tag selection prompt, you will be
>     switched to a completion interface to select a tag.  This is
>     useful when you want to select a tag that does not have a
>     direct access character.
>
>     A double `/ /' will restore the original agenda view by
>     unhiding any hidden lines.
>
>     This functionality was John Wiegley's idea.  It is a simpler
>     implementation of some of the query-editing features proposed
>     and implemented some time ago by Christopher League (see the

> Editing fixed-width regions with picture or artist mode
> -------------------------------------------------------
>
>     The command C-c ' (that is `C-c' followed by a

>     editing mode for fixed-width sections.  The default mode is
>     `artist-mode' which allows you to create ASCII drawings.
>
>     It works like this: Enter the editing mode with

>     editing, and then added back when you exit the editing mode.

> Tags can be used to select the export part of a document

>     changed, even to include a list of several tags.

>     be selected for export.  Finally, all subtrees that are
>     marked by any of the /exclude/ tags will be removed from the
>     export buffer.
>
>     You may set these tags with in-buffer options
>     `EXPORT_SELECT_TAGS' and `EXPORT_EXCLUDE_TAGS'.

> In column view, date stamps can be changed with S-cursor keys

> Agenda views can sort entries by TODO state
> -------------------------------------------
>
>     You can now define a sorting strategy for agenda entries that
>     does look at the TODO state of the entries.  Sorting by TODO
>     entry does first separate the non-done from the done states.
>     Within each class, the entries are sorted not alphabetically,
>     but in definition order.  So if you have a sequence of TODO
>     entries defined, the entries will be sorted according to the
>     position of the keyword in this sequence.
