        Many of the configuration and switch variables can be globals
because main() and the functions for reading the cfg and rc files are
called only once, and modify then according to priority rules.  The
important thing is to declare them in LYMain.c and LYGlobalDefs.h,
and keep them grouped together, so you can find them and make sure you
are not re-inventing wheels in conjunction with making enhancements
or adding new features.  LYUseDefNoSelPop could have been passed as
an argument between main() and parse_arg(), or been made a PRIVATE
global in LYMain.c, but since we now have a PUBLIC select_popup
global, I declared the whole set of variables PUBLIC and grouped
them together in LYMain.c and LYGlobalDefs.h.
