cg-update does not work with argument specified

Documentation/tutorial-script/script.sh line 117 fails when trying to execute cg-update bobswork

The error message is: cg-fetch: where to fetch from?

Quick investigation showed that cg-update runs cg-fetch as: cg-fetch "$force" "$name"

When tried it manually with cg-fetch "" bobswork got the same error. Removing "" works fine.

Further investigation showed that cg-fetch uses name="${ARGS[0]}" line to find out branch name but ARGS[0] contains empty string.

Probably something should be fixed about lines 391-404 in cg-Xlib where ARGS is set but I do not know this bash feature so unfortunately can't write patch myself.

Hope this helps.

P.S. Please Cc: me I'm not following the list closely.
