Summary: use awk instead -- it's trivial

awk '/^BEGIN$/ { wantthis = 1; next }
/^END$/ { wantthis = 0; next }
{ if(wantthis) print $0 }'

The test for BEGIN can be augmented to spit out a dividing line of
some sort, if that's desired. Note that the line beginning with '{'
matches ALL lines.

I must confess that I programmed in C on UNIX systems for 11 years
before finally learning awk.  Should have gotten into it far sooner.
Awk is a tremendous tool, once you figure out how to use it.  (It's
a bit like pointers in C: one day it suddenly clicks.)
