A bug has been fixed that resulted in the NDF AUTOHISTORY facility being switched off
inside an NDG “group history” block. For instance, this caused all KAPPA applications
to ignore any value set for environment variable NDF_AUTO_HISTORY.
New routine NDG_ABPTH added to convert a group of NDF paths from relative to
absolute (with respect to the current working directory).
Routine NDG_GTSUP now returns field values formed by parsing the file specifications
in the supplied group, if the supplied group has no supplemental information. Previously,
it returned blank field values in such cases.
