No, the opposite.  I want a solid line, but I always get a dashed line:



startTextSpanner = #(make-span-event 'TextSpanEvent START)
stopTextSpanner = #(make-span-event 'TextSpanEvent STOP)

\score {
  \context Voice \transpose c c' {
    f a c' bes a g f g f
    \startTextSpanner
    g a bes
    \stopTextSpanner
    a g f f
  }
  \paper {
    \context {
        \Voice
        \override TextSpanner #'style = #'line
        \override TextSpanner #'edge-height = #'(0 . 0)
        \override TextSpanner #'padding = #0.5
        \override TextSpanner #'enclose-bounds = #1
        \override TextSpanner #'edge-text = #'("abc" . "def")
    }
  }
}



The above code produces a dashed line instead of a solid one.  Actually, 
it seems there are at least two bugs, because even if I change 
Line_interface::line () such that the else branch is entered for solid 
lines (by removing the "scm_is_number (dash_fraction)" clause in the if 
condition), I still get a dashed line.  BTW, why is make_line (...) 
defined in Line_interface rather than in Lookup?

This bug is relevant for me, because it breaks the episem feature of 
ancient notation.
