56b933f4a2 Instead of declaring our own err() which is different than the standard one, 
and using it incorrectly in a few places because of confusion (does it print
errno or not?), declare two versions following the standard ones xerrx and,
xerr, and use those as appropriate, implementing them using them vwarn and
vwarnx.

not break from the loop, only from the switch. Make it break from the
loop to avoid a NULL pointer dereference.

8bfad4ad7a Use sleep(1) instead of usleep(1000000) to sleep for a second, since 
usleep() doesn't support an argument >= 1000000.

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

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.

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.
