Two more notes: StudlyCaps are not the style used for markup commands,
you'd use contemp-sign for the markup.  And putting the path in a
separate variable to keep the markup macro from messing with it seems
awkward.

There is also no need for an option-less markup command.

And putting this together with some goodness from the current release
candidate for the next stable version (and assuming that the sign
belongs up by default as a postevent) we get

\version "2.15.30"


#(define-markup-command (contemp-sign layout props) ()
   (interpret-markup layout props
     #{ \markup \override #'(filled . #t) \path #'0.25
              #'((moveto 0.0 0.0)
                 (curveto -1.1 1.1 -0.5 1.5 0.5 0.5)
                 (lineto 1.1 1.1)
                 (closepath))
     #}))

contempSign = ^\markup \contemp-sign

\relative c'' {
  c16-.\contempSign r8
}
