Another solution, which might be easier to understand. This does not 
affect the lineheight. Depending on the usage, that may or may not be 
desirable.

\unprotect
\startuniqueMPgraphic{defline}
      path p ;
      p :=
          ( 0,0) .. controls  (0,1) and ( 1,1) ..
          ( 1,1) --
          ( 6,1) .. controls  (7,1) and ( 7,1) ..
          ( 7,2) --
          ( 7,2) .. controls  (7,1) and ( 7,1) ..
          ( 8,1) --
          (13,1) .. controls (13,1) and (14,1) ..
          (14,0) ;
      draw
          p
          xysized (OverlayWidth,ExHeight)
          shifted (0,OverlayHeight)
          withpen pencircle scaled .1ExHeight
          withcolor \MPcolor{\framedparameter\c!framecolor} ;

      label.top((textext("\tfxx\color[red] \framedparameter\c!text") rotated 25),
                (OverlayWidth/2, OverlayHeight+ExHeight));

      setbounds currentpicture to boundingbox OverlayBox ;

\stopuniqueMPgraphic

\defineoverlay[curlybracket][\includeMPgraphic{defline}]

\starttext
