Hi Francisco,

This sounds but. But this might be a breadcrumb: text spanners and
glissandi now support 'bound-details 'left-broken and 'bound-details
'right-broken (sub)attributes. You can use these attributes to make
*text* go away after a line break, like in this example.

%%% BEGIN %%%

\version "2.11.25"

\new Staff {
   \override TextSpanner #'bound-details #'left #'text = \markup { "start" }
   \override TextSpanner #'bound-details #'left-broken #'text = ##f
   c'1 \startTextSpan
   \break
   c'1
   c'1 \stopTextSpan
}

%%% END %%%


Unfortunately, I don't know how to make the *spanner itself* disappear
after the line break ...
