More trace code.
Merge branch 'rev'
Update minimal.html to reflect revised operand order for add,anb,mov,orb,sub, and xob.
Cleanup x32 files, especially the header files.
More refinement of ./x32 files, with some dead stuff deleted. Refine trace. Save spitbol.S,
the spitbol.s before operand reversal of selected ops.
Reverser order of first two operands of aov so result is first.
Fix problems with memmem() in translator to handle new operand order of selected ops.
Merge branch 'master' of http://github.com/hardbol/spitbol
Fix problem in memmem() with comparison operations.
Remove fake 'exit' procedure from ./os files; just use standard exit().
Clean up summary output from lex.spt, x32/min2asm.spt and x32/err.spt
Modify ati trace so that arg of 0 turns off instruction tracing, -1 turns it on.
Eliminate some dead trace-related variables

More work on trace code.
Try simpler approach to initializing stack. Move save file / load module code to new file
x32/module.s (for later debugging).
Have lexer collect counts of ppm, erb, and err operators.
To improve readability, reorder source order of x32/sys.s to bring ccaller closer to top.
Refine handling of jsr,ppm,erb,err instructions.
Revise handling of sys.. calls. Simplify handling of 'exi' instruction.
Refine handling of exi instruction.
Extract documentation from MINIMAL source for SPITBOL, convert it to HTML format
from plain text, and include result in minimal.html
Also include some sample code in the reference document to show the flavor of the code.
Change name minimal.html to minimal-reference-manual.html.
This file now includes an introduction with some sample excerpts to
give a sense of the flavor of the code, as well as the specifiation
of the osint (sys??) operating system interface procedures.
