Among the flaky tests, it seems that the Azure Pipeline suffers relatively frequently from t5516 failing with the Visual Studio builds. Essentially, we grep for an error message, but that error message is produced twice, once by a fetch and once by the upload-pack spawned from it, and those error messages are usually interleaved because of MSVC runtime fprintf() idiosyncracies. The commit message of this patch is based, in part, on https://github.com/gitgitgadget/git/pull/407. The patch itself is a much more minimal alternative (using xwrite() instead of fprintf()) to the code of https://github.com/gitgitgadget/git/pull/407, avoiding the complexity of the part of the code that allows for unlimited messages. While it would seem theoretically more elegant to allow for unlimited messages, in practice too-long messages cause more problems than they solve, and therefore we already clip them, and this patch does not change that behavior. This fixes https://github.com/gitgitgadget/git/issues/240.
