Comment #10 on issue 3888 by address@hidden: Completion_heads_engraver  
hangs after \time in mid-measure
http://code.google.com/p/lilypond/issues/detail?id=3888#c10

Fix infinite loop in Completion_heads_engraver at invalid measure position  
(issue 3888).

* Completion_heads_engraver now gives a programming_error instead of trying  
to make negative-duration notes.
* intlog2 with a nonpositive argument now gives an error instead of an  
infinite loop.

Warn when \time is used in mid-measure, and reset measurePosition so it  
stays valid.

This makes issues 3696 and 3888 less mysterious.
