Temporally/occasionally turn off hooks?

[Thorsten Jolitz <tjolitz@googlemail.com>]

Hi List, 

I copied this from Bernt Hansens set-up:

,-----------------------------------------------------------
| org-insert-heading-hook is a variable defined in `org.el'.
| Its value is (bh/insert-heading-inactive-timestamp)
| Original value was nil
`-----------------------------------------------------------

and its often quite usefull to have a timestamp for each newly inserted
todo-item (e.g.). But in other cases, like writing documents or building
Org files programmatically, there is no need for
heading-creation-timestamps, so I would like to turn the timestamp
insertion off. 

I could probably use 

,-----------------------------------------
| (remove-hook
|    'org-insert-heading-hook
|    'bh/insert-heading-inactive-timestamp
|    ’LOCAL)
`-----------------------------------------

to deactivate the behaviour locally, since:

,------------------------------------------------------------------------
| remove-hook is a compiled Lisp function in `subr.el'.
| 
| (remove-hook HOOK FUNCTION &optional LOCAL)
| 
| Remove from the value of HOOK the function FUNCTION.
| HOOK should be a symbol, and FUNCTION may be any valid function.  If
| FUNCTION isn't the value of HOOK, or, if FUNCTION doesn't appear in the
| list of hooks to run in HOOK, then nothing is done.  See `add-hook'.
| 
| The optional third argument, LOCAL, if non-nil, says to modify
| the hook's buffer-local value rather than its default value.
`------------------------------------------------------------------------

but this is of course not a very generic solution for a program I want
to share with others, their 'org-insert-heading-hook' might look
different. 

Is there a way to inhibit a hook in a program, or to run it only
conditionally in certain situations?
