PATCH: remove unused variables and code in value_assign

[Jim Blandy <jimb@redhat.com>]

Committed as obvious.

2004-09-13  Jim Blandy  <jimb@redhat.com>

	* valops.c (value_assign): 'use_buffer' is initialized to zero,
	and never assigned to.   Delete it, and the 'if (use_buffer)'
	clauses.  Delete 'raw_buffer', since it is now unused.
