dispatch: convert non-list option parsed by _earlygetopt() to string
So we can easily compare it with the corresponding getopt() result.
There's a minor behavior change. Before, "hg --cwd ''" failed with ENOENT.
But with this patch, an empty cwd is silently ignored. "hg -R ''" has always
worked as such, so -R has no BC.
