Hello,
I think that at the moment, the introduction for varobj has a number of problems:

	- It does not mention update operation, which is 50% of varobjs relevance
	- It does not adequately describe hierarchy of varobjs, in particular that
	only leaf varobjs hold real data and can be manipulated.
	- There's a paragraph about hex/decimal format, which is minor
	detail and need not be mentioned.
	- The grammar of the text is overly complex sometimes.

The attached patch basically rewrites the introduction. The semantic of -var-update
is also clarified. The new introduction is basically one blob of text. There are places
where docbook <firstterm> would be appropriate, but it looks to be not supported
in info.

Comments?

	* gdb.texinfo (GDB/MI Variable Objects): Improve the 
	introduction.  Specify -var-update more exactly.
