Inconsistent behavior when Argcfile.sh is a symlink

[CGamesPlay]

Hi sigoden, I was recently setting up a repository where I needed to symlink the Argcfile into a different location. I wanted to do this specifically because I wanted argc's directory handling (so that the script would always be run from the directory with the symlink).

The behavior I observe:

• argc --argc-script-path prints the path to the symlink
• argc will cd into the directory containing the target of the symlink.

I feel like one of these exhibits the wrong behavior. For me, I'd prefer that argc did not resolve the symlink before changing directory (since I can't imagine a time when that behavior would be useful), but if this is desired behavior, then --argc-script-path should be consistent with it.

Thanks as always for the great software package.
