I have run into a couple of anomalies with the \articulate command and the 
abbreviation "rit."

First,

\version "2.19.15"
\include "articulate.ly"

\score{ 
    \unfoldRepeats \articulate
    \new ChoirStaff <<
        \new Staff c-"rit."
        \new Staff c-"rit."
    >>
    \layout { }
    \midi { }
}

throws a warning:       warning: Two simultaneous tempo-change events, junking 
this one
                                warning: Previous tempo-change event here

If "rit." is replaced with "\markup { "rit." }, no warning is thrown. Section 
"1.8.1 Writing text" pretty much implies that those two ways of generating text 
are equivalent.

I don't think this warning should occur.  Isn't it a common thing to place such 
a notation in all staves so that if parts are generated, each part will have 
the notation.

Second,

\version "2.19.15"
\include "articulate.ly"

music = \relative c'' { \repeat unfold 21 { c d e f} c-"rit." d e f \repeat 
unfold 6 { c d e f }}

\score { {
    \unfoldRepeats \articulate
    \new Staff \music
  }
  \layout { }
  \midi { }
}

generates a midi file that begins with the tempo "4=60" (the default) and then 
changes to "4=36" at measure 22 and remains there for the remainder of the midi 
file.  if "rit." is replaced with \markup { "rit." } the tempo is a constant 
4=60 for the whole midi file.

I think the most disturbiing thing is that \articulate is interpreting "rit." 
to mean "ritenuto" rather than "ritardando", which I think is the most common 
interpretation of "rit.".  It would be great if the tempo would ramp down 
gradually to "4=36" at the end.
