	Improving LilyPond's output to make them ordinary TeX boxes with
	predictable dimensions.  System boxes are now vertically centered on
	the baseline; this offset can be further controlled with
	\lilypondscoreshift.

	* lily/system.cc (System::post_processing): Pass length of current
	system to `start-system' (including any horizontal indentation).

	* scm/tex.scm, scm/pdftex.scm: Make output of various functions
	prettier.
	(lily-def): Append `%'.
	(start-system): Add parameter `wd'.  Output more TeX code to specify
	box dimensions.
	(stop-system, stop-last-system): Complement changes in
	`start-system'.
	* scm/sketch.scm, scm/ps.scm, scm/pdf.scm, scm/ascii-script.scm:
	Updated.

	* scripts/ly2dvi.py (global_latex_definition): Set \parindent to 0.
	* buildscripts/mf-to-table.py (write_tex_defs): Append `%'.
	Write final `\endinput'.

	* tex/lily-ps-defs.tex, tex/lily-pdf-defs.tex,
	tex/lilypond-plaintex.tex, tex/lilypond-latex.tex,
	tex/lilyponddefs.tex, tex/titledefs.tex: Reformat code.  Assure that
	files and macro definitions don't produce spurious spaces and
	paragraphs (using \endlinechar).
	* tex/lilyponddefs.tex: New dimension `\scoreshift'.

	* Documentation/user/internals.itely: Improved formatting, fixing
	typos
	Added a section `Output details' to describe how the TeX code
	looks like.
