commit 5c0ab198bd9dc104f8f15969c32d8df70c86e0fa
from: Omar Polo <op@omarpolo.com>

use NL_TEXTMAX for the strerror_r buffer

the strerror_r(3) man page mentions that it returns a message that's up
to NL_TEXTMAX bytes long (including the NUL.)  strerror_r can fail with
ERANGE if the buffer is not large enough, and that's probably the case
of some "funny" Rerrors that cage gets from time to time.
