Pull in some wording to the tftpd.8 man page
from NetBSD, with some slight changes: ========================================================================================= http://cvsweb.netbsd.org/bsdweb.cgi/src/libexec/tftpd/tftpd.8?only_with_tag=MAIN#rev1.22 Revision 1.22 or diffs], Fri Jan 8 21:05:14 2010 UTC (18 months, 2 weeks ago) by christos Patrick Welche <prlw1@cam.ac.uk> - add -p pathsep option - make wrap to zero work, but produce a warning While here: - fix gcc warnings, in particular variable clobbered warnings (compiling with fewer warnings does not really fix the problem) ========================================================================================= These wording changes clarify the default rollover behavior as a "kludge". Also, the block numbers and octet counts for 65535 blocks and 32767 blocks are more accurate than the existing documented numbers.
