+Minor tweaks to Hooke's [command
+stacks](http://www.physics.drexel.edu/~wking/code/hg/hgwebdir.cgi/hooke/rev/8c0882dfbaf5). I can now execute the GUI alternative of
+
+ ./bin/hk.py
+ -c 'new_playlist'
+ -c 'glob_curves_to_playlist *'
+ -c 'start_command_capture'
+ -c 'zero_surface_contact_point --block retract'
+ -c 'stop_command_capture'
+ -c 'apply_command_stack_to_playlist'
+ -c 'curve_info'
+ -p
+
+Issues resolved today:
+
+1) GUI-generated commands clogging the command stack instead of
+ being executed. Fixed with CommandMessage.explicit_user_call.
+2) Playlist._loaded desyncronization from old 'apply command stack
+ to playlist'. Fixed with Playlist.unload().
