christos a740c3d0aa Coverity CID 3204: The USE_SLEEP case can close the fp, and break does
not break from the loop, only from the switch. Make it break from the
loop to avoid a NULL pointer dereference.

lukem 8bfad4ad7a Use sleep(1) instead of usleep(1000000) to sleep for a second, since
usleep() doesn't support an argument >= 1000000.
Problem noted & fix provided in [bin/20644] from Dave Huang.

jdolecek 64275c4aaf use kqueue to watch the file if possible
from FreeBSD via Luke Mewburn

this specifically does NOT include FreeBSD rev. 1.28 change; it's
my understanding -F is specifically meant to only detect removal
of the tailed file, not to watch for intermediate path changes

garbled 9e44e9b578 More and more .Os cleanups. .Os is defined in the tmac.doc-common file,
so we shouldn't override it with versions in the manpages.  Many more to
come.

cjs 59a47ce7be Remove tracking of file size by how many characters were output.
This succumbs to a race condition where data are written to the
file while the sleep is occurring. If a stat is done immediately
after, lastsize is updated but the file pointer wasn't pointing at
the end of the file, so the number of bytes between the current
pointer and the end of the file is added to the lastsize when
lastsize already points to the end of the file.

ghudson bd8bd7340f Don't rely on select() not to modify the timeval argument. Also,
simplify the code by passing in NULL rather than an empty fd_set to
indicate no file descriptors.
