Inline functions are created using eval_string, which is given
something like

  " at (ARGS) EXPRESSION"

where EXPRESSION is the argument passed to inline, and ARGS are the
variable names extracted from EXPRESSION.  As I recall, implementing
it this way fixed some problems with the original implementation that
tried to use the function handle class directly.

	* ov-fcn-inline.cc (octave_fcn_inline::octave_fcn_inline):
	Call eval_string instead of feval ("eval", ...).
	Construct anonymous function handle to avoid going through the
	symbol table.

	* ov-fcn-handle.h (octave_fcn_handle::fcn_val): New function.
	(octave_fcn_handle::octave_fcn_handle (const std:string&)):
	New constructor.
