Hello Patrick,

first thing: _Please_ mind the advice given with every single digest and 
edit the subject line so the e-mail may be correctly sorted into the 
thread where it belongs. I also find it quite annoying to receive 
e-mails with such cryptic subjects as this.

Does
@code{ \new Staff { \tempo %{\markup\normal-text%} "rit." }
produce the same warnings? Unlike text scripts, as in your example, 
MetronomeMarks (created by the \tempo command) are collected and 
displayed only once at the top of the score. I don’t know how this 
interacts with articulate.ly, though.

There are different opinions on this.

…which would actually require a specification on where the ritardando is 
supposed to end, which might be done either by a new \tempo indication 
or by a “tempo spanner”, which can be found on the wishlist: 
<https://code.google.com/p/lilypond/issues/detail?id=3176>. So currently 
there is no method to do this.
