[Thread] Incorrect description of effects for this_thread::sleep_for and this_thread::sleep_until

[Yasutaka ATARASHI <atara-y@…>]

In trunk/libs/thread/doc/thread_ref.qbk,

effects of this_thread::sleep_until is described as:

Suspends the current thread until the time period specified by rel_time has elapsed or the time point specified by abs_time has been reached.

while effects of this_thread::sleep_for is described as:

Suspends the current thread until the time point specified by abs_time has been reached.

rel_time in sleep_until is extra, that is description for sleep, and description of sleep_for should be for sleep_until.

[Yasutaka ATARASHI <atara-y@…>]

Thank you for the fast response.

For sleep_until,

the time period specified or

could be removed?
