Close, but no cigar.  It does not work for multiple input files.
(And, of course, spawning off a new sed for each file defeats the basic desire
of most of the people who've asked for it:  speed)

However,

	awk '/^Subject: /	{ print FILENAME ":" $0; next }' *

does (just about) work.  And it's probably not _obscenely_ slow.
(it doesn't behave for no input files, and you might prefer no FILENAME: for
just a single input file)
