.shellcheckrc is not picked up?

[petemounce]

Thank you for writing this! I'd been wondering if there was support for this (and shfmt come to that).

I have a .shellcheckrc in my repository root. It's not picked up; I validated this by adding --exclude=SC2086 to it and running against a file that violates that; that rule is still included.

I have copy/pasted to WORKSPACE and a BUILD file precisely as in README.md @ ceb47de.

Should I expect it to? My instinct is "not yet" as I don't see shellcheckrc appear in this repo.

Is there a way I can supply arguments to the underlying invocation of shellcheck, or a change I might patch in to have the rule look in the workspace-root for the config (as that's the most likely location)?
