Under some circumstances -o is passed multiple times, causing rage to fail

[lf-]

I was running agenix -i ~/.ssh/age-identities.txt -r and observed that rage was invoked wrongly.

Here is a snippet of strace output:

[pid 85487] execve("/nix/store/h5wgz7yszcnqp4x1y57abi5ha1d4fqiv-rage-0.10.0/bin/rage", ["/

Problem mysteriously vanishes in 0.15.0. Unsure why.

I am having this issue on version 0.15.0 too.
