Re: [Breakage] Git v2.21.0-rc0 - t5318 (NonStop)

If the data does not have to be a sequence of zero bytes, the
alternatives are:

* `test-genrandom seed-string $size` for a sequence of reproducible
"random" bytes

* `printf "%0*d" $size 0` for a sequence of '0' characters.

In t5318, the zero bytes do matter, though.

Also some consumers of these bytes may not be easy to read from a
pipe.
