Re: [PATCH: gdb/mi + doco] -var-update

I've changed the English slightly from last time, and because
"-var-list-children" and "-var-update" have the same optional argument, I only
describe it explictly once.  "-stack-list-locals" is slightly different
because print-values is not optional and "--print-simple-values" prints the
type also.

I've also corrected a spelling and made a couple of changes to the
GDB/MI command description format to reflect reality.

	* gdb.texinfo (GDB/MI Variable Objects): Describe print-values
	option for -var-list-children and -var-update.
	(GDB/MI Stack Manipulation): Simplify description of
	print-values option for -stack-list-locals.
