" History  Carsten Czarski (carsten dot czarski at oracle com)
"               add handling for typical SQL*Plus commands (rem, start, host, set, etc)
"               add error highlight for non-breaking space
"          Lee Lindley (lee dot lindley at gmail dot com)
"               use get with default 0 instead of exists per Bram suggestion
"               make procedure folding optional
"               updated to 19c keywords. refined quoting. 
"               separated reserved, non-reserved keywords and functions
"               revised folding
"          Eugene Lysyonok (lysyonok at inbox ru)
"               Added folding.
"          Geoff Evans & Bill Pribyl (bill at plnet dot org)
"               Added 9i keywords.
"          Austin Ziegler (austin at halostatue dot ca)
"               Added 8i+ features.
