-	* cobc.c, flags.def: add new flags to output dependencies:
-	  -foneline-deps outputs all dependencies on a single line instead of
-	  multiple lines; -fcopybook-deps outputs only copybook names instead
+	* flags.def: -fcopybook-deps outputs only copybook names instead
 	  of file paths. -fcopybook-deps also forces -E, -foneline-deps,
 	  -MT=copybooks, disables errors on missing copybooks and removes
