VISIBILITY property and C-u C-u <TAB>

VISIBILITY property and C-u C-u <TAB>

[Gez]

I've just discovered the VISIBILITY property, although I had some trouble 
working out how to apply it .I discovered C-u C-u TAB from reading 
http://thread.gmane.org/gmane.emacs.orgmode/6623.  C-u C-u TAB is documented 
in the reference card but not in the manual or on worg as far as I can see - 
Shouldn't it be added?  Also shouldn't VISIBILITY be listed with the other 
"special properties" in the manual etc?

I'm using it to mark sub-projects (level 2,3 etc) with :VISIBILITY: folded 
(or :VISIBILITY: content when they also contain a sub-sub-project). When 
sub-projects are folded into their projects (level 1) I miss out on an 
overview of all projects.  Using C-u C-u TAB I can see all non-level-1 
headlines that I've marked because they are parents of tasks, and then I can 
visit them locally with TAB.  It's very useful in conjunction with the 
counter cookie, and in column view.

I have a query about the C-u C-u TAB command.  When I've just edited or used 
S-TAB (no matter which part of the global cycle it's on) C-u C-u TAB works 
as I would expect.  But if I've just used TAB, C-u C-u TAB cycles 
hrough  -> CONTENTS -> SHOW ALL etc, even while the mini buffer displays 
"startup visibility plus VISIBILITY properties" at each stage of the cycle. 
C-u C-u TAB also cycles when it's repeated.  I find it hard to keep track of 
whether it will cycle or not while I'm using it to view areas of the 
outline, so in effect, the only way I feel sure I can quickly return to my 
desired startup visibility is with S-TAB C-u C-u TAB, which is a lot of 
keystrokes! So my questions are - is this expected behaviour?  Can it be 
changed?

Would you like to make a patch?

I believe I have fixed this, please verify.

I have also noticed this buglet and have used a workaround until now.

Thank you for this, it resolves both `C-u C-u TAB' and
`C-u C-u C-u TAB' except for the special case with the variable
org-cycle-global-at-bob. For this special case I suggest additionally:

I would like to and I read http://orgmode.org/worg/org-contribute.php#sec-3 but I don't have git.

I'm still getting the same behaviour (i.e. not fixed), using org-latest.zip which I just downloaded today from http://orgmode.org/org-latest.zip.  But my version still says Org-mode version 7.01trans so perhaps I'm not testing the fixed version.  Sorry if there's something I'm misunderstanding.

I guess only because this snapshot is not recent enough because its
update is broken. If the download contains old files like e. g. org.el
from mid of October you might read here:

If you would like to this can also be hacked without git. For the
first few patches on only one or two files I just downloaded the most
recent version of the file(s) to be changed like e. g. doc/org.texi or
lisp/org.el starting from
http://repo.or.cz/w/org-mode.git/tree
with the right most link `raw', made a copy of the file, changed the
copy and after that made a `diff -up file_original file_changed'. To
make this diff look like it came from git-diff I manually hacked the
lines with --- and +++ to look like the commitdiff that can be seen in
the history of the files on the above links and then posted this
modified patch.

Yes, fixed in my setup now (just downloaded snapshot today).  Thank you.
