[PATCH] fix some conditionals in GAS doc

[Bob Wilson <bwilson at tensilica dot com>]

This fixes some problems with conditionals.  They are fairly obvious.  One 
conditional chops off the end of a sentence.  The Skip and Space directive nodes 
are conditionalized but their menu entries are not.  The description of .line 
has a conditional to alternatively describe .ln in a node named "Ln" instead of 
"Line", but there is already an unconditional "Ln" node with its own 
conditionalized description.

This patch is relative to my previous change.  I tested it by running "make info".

OK?

	* doc/as.texinfo (Dot): Expand no-space-dir conditional to include
	a complete sentence.
	(Pseudo Ops): Put conditionals around Skip and Space menu entries.
	(Line): Remove conditional declaration of Ln node and section here.
	Put aout-bout description inside the no-line-dir conditional.
	(Skip, Space): Use a separate conditional for each node.
