I want this manual to be useful both to developers and users of TAME,
so this distinction needs to be made clear.
* doc/tame.texi (Preprocessor): chapter=>appendix.
* src/graph.texi: Top to appendix and raise subsections.
* src/symtable.texi: Top to appendix.
This makes changes necessary to new ref format (which includes arity).
* src/graph.xsl: @ref function arity added
* src/preproc/expand/expand-sequence.xsl: @ref function arity added
* tools/literate-xsl: Submodule updated
This was already happening, but formally test and document it, since
it's a very useful property.
* src/graph.xsl (graph:union): Document dedupe behavior
* test/graph-test.xsl: Add test data
* test/graph.xspec: Add dedupe test for graph:union
