Support script/ along with scripts/ by default

[jasonkarns]

GitHub's ScriptsToRuleThemAll is picking up steam as a conventional way of having scripts in a standard location across different language stacks. They use script/ as their conventional directory.

And anecdotally, a lot of nix devs I know seem to default to putting their shell scripts in script/ as well.

I don't know if script/ is some long standing convention of sysadmins or a recent conventional, but it's seemingly more common than scripts/ as a directory.

I know that the script directory can be configured manually, but convention would be better. And since script/ is the same as scripts/ in spirit ;), I propose we also allow script/ to be used by default, without the manual configuration. Implementation would just use script/ as a fallback. (Or perhaps prefer script/?) I think odds of repos having both script/ and scripts/ is virtually nil, so I don't foresee any issue with accepting either.

I'd also support migrating towards script/ as a default, and doing away with scripts/ at some point in the future. But supporting both for a while would allow for backwards compatibility.

👍 I'd support this. In fact, before reading this, I would have assumed we already named it script.

Would merge a PR that just looked up both scripts and script (and script-win, I guess)

👍🏽 I like this.
