v0.10.0 miscategorizes uncalled function as unreachable code

[matthewpersico]

For bugs

• Rule Id (if any, e.g. SC1000): SC2329
• My shellcheck version (shellcheck --version or 'online'): v0.10.0
• I tried on shellcheck.net and verified that this is still a problem on the latest commit
• It's not reproducible on shellcheck.net, but I think that's because it's an OS, configuration or encoding issue

For new checks and feature suggestions

• shellcheck.net (i.e. the latest commit) currently gives no useful warnings about this
• I searched through https://github.com/koalaman/shellcheck/issues and didn't find anything related

Here's a snippet or screenshot that shows the problem:

#!/bin/bash

main()
{
        echo I am in main
}

subber ()
{
        echo I am in subber
}

main
exit

Here's what shellcheck v0.10.0 currently says:

In /home/mpersico5/sctest line 10:
echo I am in subber
^-----------------^ SC2317 (info): Command appears to be unreachable. Check usage (or ignore if invoked indirectly).

Here's what I wanted or expected to see:

Line 8	SC2329: This function is never invoked. Check usage (or ignored if invoked indirectly).

Can we get a new release v0.11.0? I cannot bring unreleased/untagged HEAD code into my org. Thank you.

From my local testing, it appears that v0.9.0 has the same issue.
