Bug 16351 – Nonstandard output library causes no-argument writeln() to fail.

Created attachment 1605 Correction When using nonstandard output libraries such as https://github.com/sickill/stderred argumentless writeln() will fail on the enforce because it checks specifically for a new line to be returned. The error is resolved by following documentation for fputc and checking that output is not EOF, which indicates an error.

Checking instead that the output is not EOF follows the documentation and allows overridden write() functions from the standard library. https://github.com/dlang/phobos/commit/ee30556a348aede1d2523cb4d008f7eb0840a8a6 Merge pull request #4709 from andrewbenton/issue_16351 Fix issue 16351
