Large array printing patch for Fortran

[David Lecomber <david at streamline-computing dot com>]

Resubmitting this (at last) - posted originally in May.

The element printing limit for Fortran arrays is applied only for
the outer dimension of an array.  Consequently, on entering a subroutine
with an argument of a (say) 1000x1000 array, the frame will take months
to print, which kind of ruins commands like 'bt', 'info args' etc..

	* f-valprint.c: Apply array element printing limits to 
	multi-dimensional arrays
