TestSpanners seem to default to ending at the LHS of the note on which 
they terminate. If I extend the right-hand end of the spanner slightly 
by using

\once \override TextSpanner #'bound-details #'right #'padding = #-0.5

to get it to end on the RHS side of the note, then if the spanner wraps 
to a new stave, this also causes the broken spanner line to be extended 
by the same amount. I have to also add

\once \override TextSpanner #'bound-details #'right-broken #'padding = #0.5

to get around this problem. Does this qualify as a bug (i.e. if a value 
is not set for #'right-broken #'padding then it seems to automatically 
get the value assigned to #'right #'padding) or merely something that 
should be noted in the documentation. If the line in the source below 
for #'right-broken #'padding is commented out, the spanner line extends 
past the end of the stave.

\version "2.13.52"

\paper {
    ragged-last = ##t
}

\relative c'' {
    \repeat unfold 16 { c4 }
    \once \override TextSpanner #'bound-details #'left #'text = "Spanner "
    \once \override TextSpanner #'style = #'line
    \once \override TextSpanner #'font-shape = #'upright
    \once \override TextSpanner #'bound-details #'right #'text = 
\markup { \draw-line #'(0 . -1) }
    \once \override TextSpanner #'bound-details #'left 
#'stencil-align-dir-y = #CENTER
    \once \override TextSpanner #'bound-details #'right #'padding = #-0.5
    \once \override TextSpanner #'bound-details #'right-broken 
#'padding = #0.5
    \once \override TextSpanner #'bound-details #'left-broken #'text = ##f
    \once \override TextSpanner #'bound-details #'right-broken #'text = ##f
    c\startTextSpan \repeat unfold 22 { c } c\stopTextSpan
}
