I'm hoping you'll consider merging this pull request that allows for multiple values for the same flag when using a configuration file. This is already something the module supports when using command line flags.

Flag example:

-arg hello -arg world

Config example:

arg hello
arg world

Thanks!

The last time I touched this package was when Go was at 1.16.0. The intent is that this package -IS- the original go code with additions.

I'd be more inclined to upgrade the entire base to v1.20, THEN add in the multiple lines as part of that.

Is that something you are willing to PR? If so, I'm really keen on keeping as much of google's original code as is, and only changing the absolute bare minimum. If you look at past merges, you'll see I've made almost no modifications to original code except for what's absolutely necessary to call the new functions.

@jnovack I'm heading on vacation and I'll be gone for a week. I'll take a look at what that would entail when I return and get back to you.

Thanks!
