`bpipe --help` returns status code = 1

[martin-g]

Hello,

While debugging the reason for a failing test for Bioconda Mintie (bioconda/bioconda-recipes#48862) I've found out that bpipe --help started returning status code 1 in version 0.9.12.

martin@tuxedo:/tmp/mintie/LinuxArtifacts/packages/noarch/fff$ bpipe --help
OpenJDK 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.

1

It was returning 0 in the previously used version (0.9.9).

Is this change intentional ?

Thank you!
