bug fix: Jmol doesn't recognize WSL (Windows Subsystem for Linux) protocols
-- this protocol allows access from Windows to
a linux subsystem file, both for reading and writing
-- load "//wsl$/Ubuntu/home/user1/test.mol"
-- write "file://wsl$/Ubuntu/home/user1/test2.mol"
bug fix: write Jmol doesn't accept proper Windows file:// descriptions
-- vertical bar in place of colon -- "file:///C|/temp/t3.mol"
