I have found a small bug in sed v3.02.  The following sed script works
with sed v1.18, but fails with v3.02.  The purpose of the script is to
put a '-' in front of any makefile command line which starts with
'$(RMF)' and doesn't already have a '-' in front.

Script:
---------- tmp2.sed ---------------
s/^\([ 	]\+\)\($(RMF)\)/\1-\2/
---------- tmp2.sed ---------------
       ^  <-- Note: There is a real tab character here!

Data file:
---------- tmpx ---------------
realclean: clean
	$(RMF) .depend
	$(RMF) TAGS
	$(RMF) *~

distclean:
	-$(RMF) $(srcdir)/*~ $(srcdir)/mcserv $(srcdir)/*.o
	-$(RMF) $(srcdir)/core $(srcdir)/libvfs.a
---------- tmpx ---------------

Here are the results of executing sed v1.18 vs. sed v3.02:

Sed v1.18 execution:
bash.exe//h/mc-4.1.35$ sed --version
GNU sed version 1.18
bash.exe//h/mc-4.1.35$ sed -f tmp2.sed < tmpx
realclean: clean
        -$(RMF) .depend
        -$(RMF) TAGS
        -$(RMF) *~

distclean:
        -$(RMF) $(srcdir)/*~ $(srcdir)/mcserv $(srcdir)/*.o
        -$(RMF) $(srcdir)/core $(srcdir)/libvfs.a

Sed v3.02 execution:
bash.exe//h/mc-4.1.35$ sed302 --version
GNU sed version 3.02
