| 	* add-path.cc: Renamed the built-in function, pathdef, to
| 	__pathorig__, and modified the texinfo description.
| 
| 	* add-path.cc: Introduced the function restoredefaultpath() to
| 	restore Octave's path to that prior to any modifications by any
| 	of the three octaverc's.

These entries should be written like this:

	* load-path.cc (F__pathorig__): Rename from Fpathdef.
	(Frestoredefaultpath): New function.

Yes, please send the complete proposed patch.

Thanks,
