Re: [PATCH (GITK BUGFIX)] gitk: Allow safely calling nukefile from a run queue handler.

> Originally dorunq assumed that the queue entry remained first
> in the queue after the script eval, and blindly removed it.
> However, if the handler calls nukefile, it may not be the
> case anymore, and a random queue entry gets dropped instead.

> This patch makes dorunq remove the entry before calling the
> script, and adds a global variable to allow other functions
> to determine if they are called from within a dorunq handler.
