Diomidis Spinellis 91b7d6dc58 - 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
