.* TODO before 1.2
-. * rename 'staff_line_leading' (who is being lead where?) to
-staff_space, interline; (or other meaningful name) and use throughout
-lily
-
-[-> leading are the lead strips between the sticks (lines) of
-typeface. ie. leading is vertical space --hwn]

-. * move \version check to lexer.ll
-. * junk delayed spanner breaking.
-. * check dangling_scm_sym working.
-. * revise pianobrace to put font stuff into Lookup
-. * standardise(d) switches: -v, --version; -d, --debug,
-. * spacing of accidentals
-. * restorations & repeats
-. * dotted rests?
-. * input/test/grace.ly spacing (triplet!)
-. * spanners from grace to normal ctxt
-.* 4. Lyrics and grace sections don't go too well together.
- The words are aligned with the main note, not the start of the
- grace note. This is usually wrong, but is sometimes right.
-. * Auto_beam debugging output (waarom/wanneer heb jij die weggehaald?)
-. * Rename illegal to invalid
-. * Mats:
-
-- The Postscript output is still very experimental
-
-- It is impossible to typeset two textual scripts that are stacked
- on top of eachother and avoids note collisions and at the same
- time are typeset with different textStyle. I tried to move around
- the text_engraver and other engravers between Voice and Thread
- but the granularity is not fine enough, the scripts have to
- share the same engraver in order to be get correct vertical
- position but than they cannot have different style.
- In my opinion, all scripts that share the same staff, should
- be stacked vertically, avoiding collisions with the notes
- in all voices.
-
-- I'd like to change the \repetitions command to Jan's suggested
- syntax: \repeat "repeatsymbol" 2 {...}, but I'm not sure that
- I understand the implementation of repeats well enough.
-
-- The paper11/13/26 files have to be updated.
-. * Grace_slur_engraver.
-. * input/star-spangled-banner.ly: fold for lyrics?
. * Break_req handling is silly (break_forbid () + \break fucks up.)
-. * hangOnClef with non-breakable clefs.
-. * do scaled fonts generally
-. * fix partial measures in meaningful way.
-. * Michael
-
-- The two spacing bugs in the choral-1.ly I sent you earlier, small
-GIFs attached for easy reference: #1: time meter and first note on the
-line are too close; #2: last note on the line and next bar are too
-close.
-. * relative mode for midi2ly
-. *
-Crescendi/diminuendi that cross a line break lose their vertical
-position and all end up above the top staff line, see the
-following example.

+. * * auto melismaBusy for beams.
+. *In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
+ends on a pair of grace notes. Standard practice is to mark this with
+a slur starting on the main note and ending on the grace note, so a
+singer knows where to break the words.
+
+In bar 27, there's a crescendo that's supposed to start at the start
+of the grace notes and extend to the note after the grace notes.
+. * 5. Sometimes lyrics extend past the right end of the staff. I guess that
+this is a similar problem (if not another symptom of the same problem) as
+one of the spacing bugs mentioned in the TODO.
