Bugs:
Allow and handle multiple selection of files. (may need to update
listbox object to get disjoint multiple selections)

Add "busy cursor".

Make slow system commands asynchronous.

Should be able to change pwd from within gic-start.

ShowDiffOnCommit doesn't work, since showing the diff, then popping
up the editor prevents drawing of the diff window.

GIC should upgraded to Tcl v7.0 and Tk v3.3 when they are released
(hopefully Real Soon Now).


Notes:
It seems that if you add a file and commit it, other users updating
do not gain the file.

Assumes pwd is same name as module, and that pwd has a CVS subdir.

Modules may not have subdirectories.
