filecontent argument fields appear to accept multiple arguments #346
Description
I just updated to the latest commit (919e701) because I wanted to use the new type:"filecontent" feature (thank you!). It works as expected, but I notice in the help output the argument is followed by ..., which I believe implies multiple arguments could be supplied. Is this an artifact of the field type being []byte?
See <function-io> in the help output below.
$ _output/bin/linux_arm64/xfn run negz/xfn-nop:latest ~/fnio.yaml moo
