Changes made in the v4_5_1 release of ups (2000-02-17):

Changed the umask setting during temporary file creation to have group
and world write access disabled, instead of all access enabled.  Fixed
the final chmod to not allow group or world write access either.

Fixed the problem in the Bourne shell with defining aliases which end
with an ampersand.

Added a test for the sourceCompileOpt and sourceCompileReq routines to
prevent attempts to delete /dev/null.

Inhibited the attempt to report the unknown command name from errors
encountered when executing the temporary file.  This happens when user-
defined actions use commands like FileTest and there's an error.

Fixed the ups/dbconfig.template file's definition of PROD_DIR_PREFIX
to include the prd subdirectory; commented out the definition of
INFO_TARGET_DIR which is unimplemented still.
