Overriding fingering font and \markup \finger

[Nick Payne]

Is this a bug or expected behaviour? Here I am overriding the fingering 
font, but when I use \finger inside a markup, I still get the default 
fingering font rather than the font I've selected, unless I issue a 
separate font override inside the markup:

\version "2.15.20"

\relative c'' {
    \override Fingering #'staff-padding = #'()
    \override Fingering #'add-stem-support = ##f
    \set fingeringOrientations = #'(left)
    \override Fingering #'font-name = #'"Arial Black"
<e-0>8\prall^\markup { \finger "2020" }
<e-0>8\prall^\markup { \override #'(font-name . "Arial Black") \finger 
"2020" }
}
