seems to fail, though

[Geod24]

There's a few errors, some of them probably irrelevant. However this caught my eye:

1c1
< -version=someVerIdent -version=Have_describe_project -version=Have_describe_dependency_1 -version=Have_describe_dependency_2 -version=Have_describe_dependency_3 -version=anotherVerIdent

> -version=someVerIdent -version=Have_describe_project -version=Have_describe_dependency_1 -version=Have_describe_dependency_2 -version=Have_describe_dependency_3 -version=anotherVerIdent 
\ No newline at end of file
Error:  /Users/runner/work/dub/dub/test/4-describe-data-3-zero-delim.sh:111 The null-delimited dmd-style --data=versions did not match the expected output!

I don't know whether that's a change in diff or shell behavior. Anyone has a machine to test ?
