To provide an actual explanation: \mark is a music function which takes 
one argument: a number or a markup. See 
<http://lilypond.org/doc/v2.19/Documentation/notation/available-music-functions#index-mark-1>, 
to be found most easily through the LilyPond command index. This 
argument is optional, but due to LilyPond’s syntax, it can’t simply be 
omitted, but must be replaced by \default. Else whatever comes next 
would be gulped by \mark as its argument, and the difference between 
versions arose from different handling of wrong arguments.
