rtcwake: misc cleanups
Cleanups for rtcwake:
- Minor doc updates: highlight the framebuffer problem,
give correct history of this code
- Improve debug output
- Fix some linelength bugs
Note that this code predated the sysfs "wakealarm" mechanism, and
works around several now-fixed bugs in the kernel RTC framework.
Nowadays it would make sense to make this program use only the sysfs
interface to the RTC, using "since_epoch" instead of RTC_RD_TIME and
"wakealarm" instead of the four other ioctls. That could simplify
the mess involved in timezone handling.
