[PATCH 1/3] makedoc: Fix INTERNAL(|DEFINITION|FUNCTION) command definitions

[Jon Turney]

The unused INTERNAL_DEFINITION, INTERNAL_FUNCTION and INTERNAL commands are
defined in terms of the non-existent built-in 'func'

This causes every single invocation of makedoc to output "Can't find func" three
times, as it parses doc.str.

This is normally un-noticed because makedoc's stderr is redirected to a .ref
file.

Fix these unused command definitions to something with equivalent lack of
effect, but without generating an error.

	* doc/doc.str: Fix INTERNAL_DEFINITION, INTERNAL_FUNCTION and
	INTERNAL.
