Forgive me, but did I not invent that function only two weeks ago?  How 
busy have you been to have used it in so many scores?!  (:

But, really, it should involve little more than a find-and-replace to 
convert the older usage to the newer.  Here's a bash script to do the 
work:

####
#!/usr/bin/env bash
sed 's/\\override\s\+NoteHead\.color\s*=\s*\\highlightOutOfRange\s\+\('\
'#\(([^)]\+)\|\S*\)\s*\)\?\([a-z,'"'"']\+\s\+[a-z,'"'"']\+\)/\\highlig'\
'htPitches \1outside { \3 }/g' $1
####

Given an example input fragment...

%%%%
\override NoteHead.color = \highlightOutOfRange #(x11-color 'tomato) c' 
c''
\new Voice \with { \override NoteHead.color = \highlightOutOfRange #red 
c' c'' }
\relative c' { c d \once \override NoteHead.color = \highlightOutOfRange 
c' c'' e f }
%%%%

...the script outputs the following:

%%%%
\highlightPitches #(x11-color 'tomato) outside { c' c'' }
\new Voice \with { \highlightPitches #red outside { c' c'' } }
\relative c' { c d \once \highlightPitches outside { c' c'' } e f }
%%%%

But since sed works on a line-by-line basis, it will not be able to 
detect cases when you have spread the \override across multiple lines.
