Off the top of my head:
s/printf\s*\(\*(".*?").*?\);/$1;/g
Anchoring the end of the pattern with ");" should
insure you against mismatches when there is a
function call instead of a variable in the argument
list. Still, the pattern fails for weird templates
like
printf("some \"quoted\" text" ();", foo, baz, bar );
If you want to have a bullet-prrof solution, you
should check out Text::Balanced, which takes care of
stuff like balanced quotes, brackets and such.
