Workbench processes do not operate in a CLI environment, so
they cannot inherit the Workbench path, and new shells
spawned by such processes via SystemTagList() start with an
"empty" path. The function CloneWorkbenchPath() creates a
local copy of the current Workbench path, usually for the
purpose of it being passed to SystemTagList() or to
CreateNewProc() via the NP_Path tag.
