* cfg.mk (sc_some_programs_must_avoid_exit_failure): Adjust to avoid false positive. (sc_prohibit_exit_write_error): A new syntax check to prohibit open coding error(..., "write error"); instead directing to use... * src/system.h (write_error): ... a new function to clear stdout errors before we explicitly diagnose a write error and exit. * src/basenc.c: Use write_error() to ensure no repeated diagnostics. * src/cat.c: Likewise. * src/expand.c: Likewise. * src/factor.c: Likewise. * src/paste.c: Likewise. * src/seq.c: Likewise. * src/shuf.c: Likewise. * src/split.c: Likewise. * src/tail.c: Likewise. * src/tr.c: Likewise. * src/unexpand.c: Likewise. * tests/misc/write-errors.sh: Remove TODOs for the fixed utilities: expand, factor, paste, shuf, tr, unexpand.
