as well as the loop around nanosleep. Now that's in xnanosleep.c.
Allow S (in --sleep-interval=S) to be a floating point value.
- Prompted by a patch from Augey Mikus.
* src/tail.c: Include xnanosleep.h and xstrtod.h.
Move declaration of global variable, sleep_interval, to ...
(main): ...here.
Use xnanosleep, rather than sleep.
(parse_options): New parameter, sleep_interval. Update caller.
Use xstrtod, now that we accept floating point values.
