- Check and report write(2) errors.

- Issue a single writev(2) call instead of multiple write(2)s. This change improves the inefficiencies introduced when echo went on an stdio diet. The following figures are for echoing 1000 arguments. original stdio-based echo: 0.01 real 0.01 user 0.00 sys before: 0.05 real 0.00 user 0.04 sys after: 0.01 real 0.00 user 0.00 sys

Note that -n and \c are implementation-defined as per TC1 to POSIX 2001.

traditional BSD behaviour (-n option) and FreeBSD extensions (\c).

Put echo on a diet, removing unnecessary use of stdio and getopt.

clarify code:

2002-03-04T05:30:04Z

add comments. don't get the length of each arg passed, only the last one. check against == or != NULL rather than using a pointer value as truth test.

Fix warnings inspired by lint, a commercial lint and WARNS=4.
