    Iv but buggy when used with IT and Ib
2.87

  Check for and allow "\ in centered page headings with P command.
  Check for and allow "\ in text dynamics with D command.
  For lyrics string starting in xtuplet, insert check for inputting musixlyr.
  For staff-crossing beamed xtuplet chords, if 2nd segment of a joined beam
    starts with a blank rest, put '\sk' into the TeX. 
    To enable high-to-both beamed etup staff-crossing chord, for blank
    rest at start of forced beam, shift \sk's from before to after \ib..;
    so \ib is at start and note in upper voice has a beam to connect to.
  Expand range of vertical xtup number shift, now stored in mult(16-22) 
  Check for and allow \" within lyrics strings, for umlauts.
2.73 (160121)
  Dirk's "..." command, to convert "text" into \pmxlyr{text}\ and insert as

  "AT" to allow Col. S.'s tuplet option. Simply input tuplet.tex and redefine
     \xnum, \unbkt, \ovbkt.

2.405: Not published but saved for safety.
  Option Aph to write \special{header=psslurs.pro} top of each page, so
    dviselec will work OK.
2.404
  Allow slur to end on rest, but not start on a rest.  Efaults height 
    of ending is default height of start (before any automatic or user-

    \mbrest's
  Enable "Rz"; define \setzalaligne in pmx.tex. Special treatment at end
    of input block before movement break, and at start of block after

2.35
  Cautionary accidentals with 'c' anywhere in note symbol.
  NEW pmx.tex with \resetsize to set size to normal or small depending on 
    current \internote.  Used with new coding in dograce() to get right
    new size in case user has \setsize'ed some lines to \smallvalue. For
    \smallvalue-sized staves, redefine \tinynotesize to give 11-pt font. 
    Affects pmx.tex.
  Continuation figure with fractional length. May now mix with other figures.
    If another figure follow Cont-fig, separate with colon.   
2.342

     onto (-1.,5.35)
  Fix ihornb bug in dodyn, seen with dynamics on lower-voice non-beamed xtups
2.32 (Noticed after posting)
  Prohibit "/" as figure.
2.32 (Posted)
  Tidied up accidentals in chords, do spacing.
  Still to do: 
      check for "(" on chord notes in spacing algo
      small accids
      double accids
      autoshift slurs
2.310
  Extra call to precrd ahead of spacing chk, and single-note crd/acc
     shifts seem OK, but not multiple.  crd/acc shifts not recorded 1st time. 
2.309
  Alternate algo for accid shifts in chords.
2.308
  Auto horiz. notehead shifting added to precrd. 
2.307
  Auto shifting of multiple accidentals in chords.
  "Ao" in main chord note to keep accidentals in order. Set nacc(28).
  If there are any manual main or chord note shifts, then
     If any manual shift is preceded by "A" then
        1. Auto-shifting proceeds
        2. "A"-shifts add to autoshifts
        3. non-"A" shifts are ignored!
     Else (>0 man shifts, none has "A")
        No auto-ordering, No autoshifts, 
     End if
  End if 
2.306
  Initialize legacy note level to middle C in case user forgets to set

    problem when >2 staves.

  Line spacing equalization.  Add macros \starteq, \endeq, \spread, etc.

    \upamt, \dnamt, \parskip).  Put \starteq on 1st note in voice 1 
    in the page, and \endeq on 1st note of next-to-last line in page.
2.28
  Flip direction of forced beam "[f..."
  Fix beam numbering for staff jumping beams. Uses irest(23,24,29,30)

  Many automatic position tweaks for letter-group dynamics and hairpins.
2.23
  Continued rhythmic shortcuts: space followed by "." or ","
