[TxMt] grammar feature request: exclude

[Matt Neuburg]

Here's a list of includes from one of the inline patterns in the AsciiDoc grammar I'm writing:

								{	include = '#double_bold'; },
								{	include = '#double_italic'; },
								{	include = '#double_literal'; },
								{	include = '#double_unquoted'; },
								{	include = '#double_quote'; },
								{	include = '#single_bold'; },
								{	include = '#single_italic'; },
								{	include = '#single_literal'; },
								{	include = '#single_literal_nopassthru'; },
								{	include = '#single_unquoted'; },
								{	include = '#superscript'; },
								{	include = '#characters'; },

But it happens that that list is almost the same as the #inline group I've already defined. I could reduce this to a single include! There's just one problem: we must not include ourselves, i.e. #subscript; we crash if we do, and anyway it's wrong (this pattern is not in any way recursive). Thus I request that the grammar should allow me to talk like this:

								{	include = '#inline'; },
								{	exclude = '#subscript'; },

This is not just to make the list shorter; it also makes the list more correct and coherent, because I'm allowed to say (and see) exactly the truth: "include everything except yourself".

Thanks for thinking about this - m.
