In the first bar I've fudged having the spanner on a single note by 
using a silent grace note on which to start the spanner:

\version "2.15.32"

eightva = #(define-music-function (parser location dirn shorten adjBreak 
adjEnd)
    (number? pair? number? number?)
#{
    \once \override TextSpanner #'bound-details #'left #'text = 
\markup\tiny { \concat { 8 \lower #1 \italic\super "va" } }
    \once \override TextSpanner #'font-shape = #'upright
    \once \override TextSpanner #'direction = #dirn
    \once \override TextSpanner #'dash-period = #0.8
    \once \override TextSpanner #'dash-fraction = #0.6
    \once \override TextSpanner #'thickness = #0.8
    \once \override TextSpanner #'bound-details #'right #'text = 
\markup { \draw-line #(cons 0 (/ dirn -2)) }
    \once \override TextSpanner #'bound-details #'left 
#'stencil-align-dir-y = #CENTER
    \once \override TextSpanner #'bound-details #'left #'padding = 
#(car shorten)
    \once \override TextSpanner #'bound-details #'right #'padding = 
#(cdr shorten)
    \once \override TextSpanner #'bound-details #'right-broken 
#'padding = #adjEnd
    \once \override TextSpanner #'bound-details #'left-broken #'X = 
#adjBreak
    \once \override TextSpanner #'bound-details #'left-broken #'text = ##f
    \once \override TextSpanner #'bound-details #'right-broken #'text = ##f
#})

\relative c'' {
    c4 \eightva #UP #'(0.5 . -1.5) #7 #0.5 \grace s8\startTextSpan 
c'4\stopTextSpan c, c
    c4 \eightva #UP #'(-0.8 . -1) #7 #0.5 c\startTextSpan c\stopTextSpan c
}
