Simplify handling of command-line verbose option:

Previously, there was a $VERBOSE script variable that was set according to
the "-v" command line option and then reset to null within each source
sub-shell.  With no loss of functionality, this patch removes all references
to that variable.

This makes the script 13 lines shorter.
