	windows around to show it to them.  Being prompted to resolve an
	idle clock should be as inobtrusive as possible.
	(org-resolve-clocks-if-idle): New function that resolves only the
	currently active clock if the user has exceeded the time returned
	by `org-user-idle-seconds', based on the value of
	`org-clock-idle-time'.
	(org-clock-in): If, after resolving clocks,
	(org-clock-out): Cancel the `org-clock-idle-timer' on clock out.

	* org-clock.el (org-clock-resolve-clock): New function that
	resolves a clock to a specific time, closing or resuming as need
	be, and possibly even starting a new clock.
	(org-clock-resolve): New function used by `org-resolve-clocks'
	that sets up for the call to `org-clock-resolve-clock'.  It
	determines the time to resolve to based on a single-character
	selection from the user to either keep time, subtract away time or
	cancel the clock.
	(org-resolve-clocks): New user command which resolves dangling
	clocks -- that is, open but not active -- anywhere in the file
	list returned by `org-files-list'.
	(org-clock-in): Automatically resolve dangling clocks whenever a
	user clocks in.
	(org-clock-cancel): If the user cancels the solely clock in a
	LOGBOOK, remove the empty drawer.

	* org-clock.el (org-clock-idle-time): New user customizable option
	for detecting whether the user has left a clock idle.  Note: it is
	only used in this commit to test whether it's worthwhile to check
	OS X to get the Mac user's current idle time.  If the Emacs idle
	time is less than the value, the user hasn't been away long enough
	to be worth checking (a more expensive test than just getting
	Emacs idle time).
	(org-user-idle-seconds, org-mac-idle-seconds)
	(org-emacs-idle-seconds): This three functions, in conjunction
	with the user customization variable `org-clock-idle-time', return
	the number of seconds (as a floating point) that the user has been
	away from their Emacs (or, if running on OS X, their computer).

	* org-clock.el (org-find-open-clocks): New function that returns a
	list of all open clocks in the given FILE.  Note that each clock
	it returns is a cons cell of the format (MARKER . START-TIME).
	This "clock" value is used by several of the new clock module
	utility functions.
	(org-is-active-clock): New inline function which tests whether the
	given clock value is the same as the currently active clock.
	Returns non-nil if this is the case.
	(org-with-clock-position): New macro that evaluates FORMS with
	point in the buffer and at the position of the given clock.
	Changes to the current clock are global.
	(org-with-clock): New macro that evaluates FORMS with point in the
	buffer and at the position of the given clock.  However, changes
	to the current clock are local and have no effect on the user's
	active clock.  This allows, for example, far any clock to be
	cancelled without cancelling the active clock.
	(org-clock-clock-in): New inline function that switches the active
	clock to the given clock.  If either the argument RESUME, or the
	global `org-clock-in-resume', are non-nil, it will resume a clock
	that was previously left open.
	(org-clock-clock-out): New inline function that clocks out the
	given clock value without affecting the currently active clock.
	(org-clock-clock-cancel): New inline function that cancels the
	given clock value without affecting the currently active clock.

	* org-clock.el (org-clock-in): Before creating
	`org-clock-mode-line-timer', check to make sure an older timer is
	not currently running.
	(org-clock-out): Accept new third parameter `at-time', which
	permits a clock to be clocked out at a specific time.  Note that
	no attempt is made to verify that the clock out time is later than
	the clock in time.

	* org.el (org-files-list): New utility function for returning a
	list of all open org-mode buffers, plus all files used to build
	the agenda buffer.  Note that not all the files will necessarily
	be visited by a buffer at time of call.
	(org-entry-beginning-position): Like the function
	`line-beginning-position', this inline function returns the
	beginning position of the current heading/entry.
	(org-entry-end-position): Like the function `line-end-position',
	this inline function returns the end position of the current
	heading/entry.
